Resumen

Tungsten minerals which are major as Wolframite and Scheelite mineral are by-product minerals of Tin mineral known as Cassiterite. Tin minerals are mostly found in Bangka Island which is one of the islands in the Southeast Asian tin belt that makes Indonesia the largest Tin (Sn) producer in the world. This research aims to characterize the mineralogy of Tungsten and associated minerals for potential mineral processing to gain the Tungsten concentrates. The Tungsten minerals were collected from the eastern edge of Klabat Granite in Toboali District, South Bangka. The Tungsten minerals were magnetically separated up to 14000 Gauss. The magnetic and non-magnetic fractions were identified to analyze the associated mineral of Tungsten with SEM analysis. The associated minerals in the Tungsten mineralization system in Toboali were found along with Silicates, Oxides, Sulphides, and Carbonates where Silicates dominated up to 91.8% of the non-magnetic minerals while Wolframite presence up to 0.9% in the non-magnetic fraction. At magnetic fraction found that Silicates dominates also up to 84.6% while Wolframite existed at 1.1%. The results of element deportment in the non-magnetic fraction show that Tungsten is associated with iron minerals and also in liberated form. The potential Tungsten mineral is Wolframite (Fe,Mn) WO4 in the magnetic and non-magnetic fraction. Mineral locking at P100 size 18.8 μ. shows that 84.4% Wolframite was locking with 3 (three) other minerals, 10.4% locking with 2 (two) other minerals, and only 4.8% Wolframite was 100% free in the magnetic fraction while in non-magnetic fraction P100 size 31.5 μ 77.5% Wolframite was locking with 3 (three) other minerals 18.3% locking with 2 (two) other minerals and only 4.2% Wolframite was 100% free. The processing concept is to liberate Tungsten from the associated minerals either with comminution or a combination of roasting alkali and leaching process and concentrate it up to marketable Tungsten concentrates.

Resumen

In Russia and globally, pulsed power technologies have been proposed based on the conversion of energy into a short-pulsed form and exposing geomaterials (minerals, rocks, and ores) to strictly dosed high-power pulsed electric and magnetic fields, beams of charged particles, microwave radiation, neutrons and X-ray quanta, and low-temperature plasma flows. Such pulsed energy impacts are promising methods for the pretreatment of refractory mineral feeds (refractory ores and concentration products) to increase the disintegration, softening, and liberation performance of finely disseminated mineral complexes, as well as the contrast between the physicochemical and process properties of mineral components. In this paper, we briefly review the scientific foundations of the effect of both high-power nanosecond electromagnetic pulses (HPEMP) and dielectric barrier discharge (DBD) in air on semiconductor ore minerals (sulfides, rare metals minerals) and rock-forming dielectric minerals. The underlying mechanisms of mineral intergrowth disintegration and changes in the structural and chemical states of the mineral surface when exposed to HPEMP and DBD irradiation are discussed. The high performance and potential limitations of pulsed energy impact and low-temperature plasma produced by DBD treatment of geomaterials are discussed in terms of the directional change in the process properties of the minerals to improve the concentration performance of refractory minerals and ores.

Resumen

Surface phenomena play the crucial role in the behavior of sulfide minerals in mineral processing of base and precious metal ores, including flotation, leaching, and environmental concerns. X-ray photoelectron spectroscopy (XPS) is the main experimental technique for surface characterization at present. However, there exist a number of problems related with complex composition of natural mineral systems, and instability of surface species and mineral/aqueous phase interfaces in the spectrometer vacuum. This overview describes contemporary XPS methods in terms of categorization and quantitative analysis of oxidation products, adsorbates and non-stoichiometric layers of sulfide phases, depth and lateral spatial resolution for minerals and ores under conditions related to mineral processing and hydrometallurgy. Specific practices allowing to preserve volatile species, e.g., elemental sulfur, polysulfide anions and flotation collectors, as well as solid/liquid interfaces are surveyed; in particular, the prospects of ambient pressure XPS and cryo-XPS of fast-frozen wet mineral pastes are discussed. It is also emphasized that further insights into the surface characteristics of individual minerals in technological slurries need new protocols of sample preparation in conjunction with high spatial resolution photoelectron spectroscopy that is still unavailable or unutilized in practice.

Resumen

In mineral processing, arsenic-bearing minerals are particularly difficult to separate from their non-arsenic counterparts because they possess similar surface properties. Peptides are well known for their target specificity and can offer a ‘green’ alternative to traditional flotation reagents. However, the use of peptide technologies in mineral processing for developing novel flotation reagents has not been explored. Hence, this work aims to develop a screening method to identify mineral-binding peptides as potential reagent candidates. It is hypothesised that peptides can selectively adsorb onto mineral surfaces, and this method can efficiently identify mineral-binding peptides with high specificity toward the target minerals. The methodology presented involves a selection of peptide candidates from existing literature that show affinity toward arsenic species. These peptides were tested for their adsorption performance onto selected mineral surfaces to evaluate their mineral selectivity under flotation conditions. The study demonstrates that the screening method developed is effective in identifying peptides that have an affinity for target minerals, in this case, arsenic minerals. The screening method can be applied to other minerals, thus, unlocking the potential for developing new reagent chemistries for use in mineral processing.

Resumen

Increasing environmental concern forces the reduction in the share of synthetic surfactants in the production of various industries, including mineral processing, by replacing them with more environmentally friendly compounds of biological origin. Several studies on the use of biosurfactants in mineral processing are currently available in the literature, but they contain limited information related to the physicochemistry of these processes. Therefore, this review aims to summarise publications from the last decade related to the role of microorganisms and their metabolic products in mineral surface modification applied in mineral processing. Theoretical principles of bacteria–mineral interactions are presented. Salt-type, sulphide, and oxide minerals were discussed with greater attention to the physicochemistry of biosurfactant–mineral interactions, such as the wettability and surface charge. The advantages and disadvantages of using bacterial cells and surface-active microbial compounds were proposed. The trends and challenges of biomodification in flotation and flocculation were discussed.

Resumen

The chemical component, mineral composition and dissemination characteristics of Xuanhua iron ore are researched systematically. The result shows that: the iron ore mainly is oolitic structure and colloform, xenomorphic granular texture, the mineral composition is complex, the primary metallic minerals is hematite, and the rocky minerals mainly is quartz, followed by carbonate, epidote, chlorite, and amphibole. The diffraction size of hematite and rocky minerals is fine. It is difficult to liberate between hematite and rocky minerals and easy to be mud. The iron ore is very hard to separate, and it can be used in the process of stage grinding and concentration.

Resumen

In order to produce valuable minerals and gangue, mineral processing primarily entails the separation of minerals through specific unit operations and processes, which are often characterized by physical and chemical separation. For the concentration of fine heavy minerals with particle sizes as small as 0.5 mm, gravity separation techniques have been shown to be the most effective and cost-effective method; below this size, the effectiveness of separation decreases significantly in the absence of external pressures. This is without a doubt one of the most well-known and traditional methods in mineral processing for separating a wide range of minerals with densities ranging from the highest 7.50 (like galena) to the lowest 1.30 (typical of coal). Many gravity separators that utilize the density difference feature are currently accessible thanks to recent technological advancements. It has been noted that new technologies are being developed to separate minerals with fine and ultrafine sizes using air, water, and heavy fluids or media for enrichment. Some gravity separators were investigated in the current study, and some are now in use in pilot plants, industries, and have been suggested as ways to improve gravity separators.

Resumen

Processing sulfur containing minerals is one of the biggest sources of acute anthropogenic pollution particularly in the form of acid mine drainage. Sulfur-based minerals are generally roasted to convert them to the oxide, producing SO2 or leached in acid producing H2S. This study attempts to show an innovative method for processing sulfide-based minerals using a deep eutectic solvent (DES), Ethaline, which is a mixture of choline chloride and ethylene glycol. It is shown that pyrite can be solubilised by both electrochemical oxidation and reduction in a DES. A novel method is demonstrated to investigate the redox properties of minerals using a paste made from the mineral powder in a DES. The first bulk electrochemical dissolution of pyrite is shown without the formation of H2S or SO2. The solubilised species are investigated using cyclic voltammetry UV-vis spectroscopy and EXAFS. In all cases for the iron minerals studied, it was found that the electrochemistry of the counter ion and not the metal, controlled the ease of dissolution. It is also shown that the soluble species, including elements such as arsenic, can be recovered electrochemically which could potentially decrease acid mine drainage. The electrochemical properties of other iron–sulfur and iron–arsenic minerals are also presented and compared to those of pyrite. The final part of this study uses different cell designs in an endeavour to optimise the space-time-yield of the electrochemically assisted digestion of jarosite. It was found that the electrochemical digestion of material was up to 20 faster than the chemical dissolution. It was, however found that formation of insoluble precipitates, particularly of lead and zinc sulfates affected the performance of the separator membranes and this could decrease the yield of digested metal. The presence of high concentrations of iron salts led to passivating films on the zinc surface during cementation.

Resumen

This PhD thesis investigated the influence of kaolin and bentonite clays in the ore on flotation, filtration and centrifugal concentration. The results showed that the presence of particularly bentonite in the ore had a detrimental effect on flotation and filtration. The information generated from this work will advance our knowledge as well as provide important information for plant metallurgists. The project, therefore, is essential for the mineral industry that process clay-containing ores.

Resumen

The purpose of this dissertation is to evaluate the feasiblity of alumina production in Ghana to replace imported alumina for the production of aluminum. It spells out the conditions which led to the existing bauxite-alumina-aluminum trade in the country. The structure of the economy of Ghana is examined to show the contributions of the important sectors to the total income of the country, and its dependence on a few export commodities for revenue. The plan to build a dam for the generation of hydroelectric power was linked to the establishment of an integrated aluminum industry based on the exploitation of domestic bauxite reserves. As the country could not finance the project alone, foreign assistance was sought. VALCO, a subsidiary of Kaiser and Reynolds, was formed to undertake the project. The agreement reached with VALCO was that a smelter would be built to use imported alumina for ten years, during which time a refinery would be built to feed the smelter from domestic sources. However, after ten years this could not be achieved, and the smelter continues to use imported alumina. A model of the world aluminum economy is used for analyzing the sensitivity of price to production and consumption expansion. The results show that industry demand is sensitive to the level of industrial activities in the developed countries, and less sensitive to the own price and cross price variables of aluminum in both the short and long run. On the other hand, supply is inelastic to the own price and the rate of capacity utilization in the short run, but elastic to both variables in the long run. An appraisal of opening a bauxite mine and an alumina refinery at Kibi is undertaken. The results show the levels of bauxite and alumina prices and the costs of construction at which the project is feasible. The shadow values and weights used are permittd to vary with changes in the economy's foreign trade and the balance of payments.

Resumen

Pearl millet is an important staple food in rural Africa. However, the mineral bioavailability of pearl millet is low due to its high content of antinutrients, particularly phytate. This research investigated the effects of mineral biofortification, steeping/lactic acid fermentation and parboiling alone and in combination with abrasive decortication of pearl millet grain on its mineral and antinutrient contents. Six normal varieties and two mineral biofortified hybrids were investigated. There was considerable variability in mineral content among the varieties. Iron content ranged from 3.0 to 9.6 mg /100 g and zinc from 3.0 to 4.8 mg /100 g. The mineral biofortified hybrids Dhanashakti and ICMH 1201 had substantially higher iron (21-68%) and zinc (15-39%) contents compared to the normal varieties. Phytate content differed substantially, with levels from 830 to 1360 mg /100 g. There was no definite trend between the phytate content of normal and mineral biofortified types. Decortication did not cause significant losses in zinc, but resulted considerable iron losses (mean 31%) across the varieties. There were minimal effects of steeping/lactic acid fermentation and parboiling on iron and zinc contents. Mineral biofortified hybrids were associated with high iron and zinc content after all processing treatments. Decortication of raw grain substantially reduced phytate (mean 24%) and by a further 12 percentage points when applied after steeping/lactic acid fermentation. Parboiling plus decortication was less effective in reducing phytate content. The critical phytate: iron molar ratio of <1, above which iron absorption is seriously impaired, was not achieved with any of the processes. However, steeping/lactic acid fermentation plus decortication and parboiling plus decortication reduced the phytate: zinc molar ratio to below the critical level of <15 in some varieties. Generally, the mineral biofortified hybrids had improved phytate: mineral molar ratios than the normal varieties for both raw and processed grains. Decortication greatly reduced total phenolic content (mean 24%) across the varieties and by an additional 14 percentage points after steeping/lactic fermentation and parboiling. Abrasive decortication in combination with steeping/lactic acid fermentation is an effective way of reducing phytate content in pearl millet grain, and hence somewhat improving estimated iron and zinc availability. It is recommended that the process is utilised to a greater extent in pearl millet food processing. Parboiling is also effective in phytate reduction, and can be adopted. Because mineral biofortified pearl millet hybrids have much higher iron and zinc contents, their breeding and cultivation should be promoted in rural Africa.

Resumen

Surface spectroscopic techniques have been applied to facets of the flotation beneficiation and hydrometallurgical extraction of sulfide minerals to enhance the fundamental understanding of these industrially important processes. As a precursor to the determination of surface chemical composition, the sub-surface properties of some sulfide minerals that have not previously been fully characterised were also investigated. The electronic properties of ??-NiS and ??-NiS (millerite), Ni3S2 (heazlewoodite), (Ni,Fe)9S8 (pentlandite), CuFe2S3 (cubanite), CuFeS2 (chalcopyrite), Cu5FeS4 (bornite) and CuS (covellite) were investigated by conventional and synchrotron X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy augmented by ab initio density of state calculations and NEXAFS spectral simulations. Particular aspects studied included the relationship between sulfur coordination number and core electron binding energies, the higher than expected core electron binding energies for the sulfur in the metal-excess nickel sulfides, and the formal oxidation states of the Cu and Fe in Cu-Fe sulfides. It was concluded that the binding energy dependence on coordination number was less than previously believed, that Ni-Ni bonding was the most likely explanation for the unusual properties of the Ni sulfides, and that there was no convincing evidence for Cu(II) in sulfides as had been claimed. Most of the NEXAFS spectra simulated by the FEFF8 and WIEN2k ab initio codes agreed well with experimental spectra, and the calculated densities of states were useful in rationalising the observed properties. XPS, static secondary ion mass spectrometry (SIMS) and NEXAFS spectroscopy were used to investigate thiol flotation collector adsorption on several sulfides in order to determine the way in which the collector chemisorbs to the mineral surface, to differentiate monolayer from multilayer coverage, and to characterise the multilayer species. It was found that static SIMS alone was able to differentiate monolayer from multilayer coverage, and together with angle-resolved NEXAFS spectroscopy, was also able to confirm that 2-mercaptobenzothiazole interacted through both its N and exocyclic S atoms. The altered layers formed on chalcopyrite and heazlewoodite during acid leaching were examined primarily by means of threshold S KLL Auger electron spectroscopy, but no evidence for buried interfacial species was obtained.

Resumen

Between 50% and 70% of the total energy used in the extraction process may be attributed to comminution. Microwave pre-treatment has been suggested as a means to decrease the energy requirements. A variety of mineral ores have been investigated and the effects of microwave radiation quantified in terms of the mineralogy, changes in the Bond Work Index, flotability and magnetic separation. It has been shown that microwave pre-treatment is most effective for coarse grained ores with consistent mineralogy consisting of good microwave absorbers in a transparent gangue (up to a 90% decrease in Bond work index for Palabora copper ore) whereas fine grained ores consisting predominantly of good absorbers are not affected as well (a reduction of only 25% in work index for Mambula ore). Although the mineralogy of minerals are affected by exposure to microwave radiation, flotability and magnetic separation characteristics have been shown not to be adversely affected, unless the microstructure is completely destroyed after prolonged microwave exposure. Computer simulations have shown that significant changes to comminution circuits are possible as a result of microwave induced work index reductions (three mills reduced to one). Purpose-built microwave units may hold the solution for more efficient mineral extraction in the near future.

‘Minerals’ is a heuristic—based computer aided design system that implements an evolutionary design methodology to synthesise mineral beneficiaring flowsheets. It has been under developement at the University of Sydney since the 1970s by various post graduate students under the guidance of Professor R. G. H. Prince. In its previous development phases, the models were improved and new process units added. As a consequence, the optimiser used by ‘Minerals’ was no longer able to function properly and a “make do” optimser was implemented.

Resumen

This research project focused on moderately thermophilic acidophilic microorganisms and their role in the oxidation of pyrite. A major objective of the work was to assess the relative efficiencies of defined combinations of moderate thermophiles in oxidising pyrite under defined conditions. In addition, various aspects of the physiology and phylogeny of moderately thermophilic acidophiles were investigated. Moderately thermophilic acidophiles, including novel acidophiles (a thermotolerant Leptospirillum and a Ferroplasma sp. ), were isolated from a commercial stirred-tank pilot plant. Pyrite oxidation by mixed cultures of different combinations of moderate thermophiles, including the novel isolates, was assessed in preliminary shake flask experiments. Data from these experiments were used to select microbial consortia in later experiments in temperature- and pH-controlled bioreactors. These involved monitoring rates of mineral oxidation, and relative numbers of the different microorganisms included in the original inoculum, using a plating technique in conjunction with a molecular approach (FISH). The results from the pyrite oxidation studies indicated that mixed populations of acidophiles may accentuate or diminish the rates and extent of pyrite oxidation, relative to pure cultures. The thermotolerant Leptospirillum isolate was found to be unable to oxidise a pyrite concentrate when grown in pure culture, though this inhibition was overcome when the iron-oxidiser was grown in mixed cultures with various Grampositive acidophiles. Investigation of the effects of fifteen individual and mixtures of flotation chemicals on moderately thermophilic acidophiles revealed different degrees of toxicities of the different reagents and sensitivities of the microorganisms, with the Leptospirillum isolate generally being the most sensitive of those tested. The phenomenon of pH-related ferric iron toxicity to moderately thermophilic and mesophilic Gram-positive bacteria was also investigated. ARDREA (Amplified Ribosomal DNA Restriction Enzyme Analysis) using the 16S rRNA gene sequences of known acidophilic bacteria, was refined and developed, and applied successfully to identify moderate thermophiles isolated from environmental samples.

Resumen

Natural minerals often lack well defined magnetic susceptibilities. Instead they must be thought of as occurring in a susceptibility range where the bulk susceptibility is affected by present impurities. Inclusions or foreign atoms in solid solution may alter a materials magnetic properties to a large extent. Mixed particles of dia andlor paramagnetic materials display a linear relationship while ferromagnetic inclusions involve a demagnetisation factor. The susceptibility distribution of value minerals in relation to gangue in the ore is the most important factor governing magnetic separation performance. Until recently, high gradient and high intensity separators of matrix type were exclusively used in wet processing. Now, new dry separators are extending the particle range for dry, fine particle separation. The capture characteristics of the matrix has been shown to change with the magnetic field strength. The separation cut is more precise at high fields, at low fields the capture probability graph cants. By superimposing the capture function on the susceptibility distribution of an ore, it is shown that materials containing value minerals at either high or low susceptibility is ideal for HGMS separation. Complex ores carrying value and gangue minerals distributed over a wide susceptibility range are unfavourable. The former situation is common in industrial mineral processing and in the upgrading of flotation concentrates. The latter susceptibility distribution is very common in complex sulphide ore feeds.

Resumen

Mining countries such as Australia and the US have recognized the lack of mineral processing engineers as the demand for mineral resources increases for energy transition and climate change mitigation. However, this need is also due to the complexity of extraction, refining, quality control, environmental impact, supply chain and regulatory requirements associated with the increased demand of minerals and metals. Within the European Union (EU), there is an acknowledged requirement for clean energy technologies that rely on critical minerals such as copper, Lithium, cobalt, nickel, and rare earth elements. Also, the EU wants to be less dependent on the supply of critical raw materials (CRM). Therefore, the demand for mineral processing engineers and metallurgists in Europe is expected to increase substantially over the next decade. However, there is not a delineated road map emphasizing the more technical and skilled professionals' education for resolving the workforce and a talent crunch in mineral processing and mining engineering-related areas. There are only a few attempts at filling the gap in education of talented mineral processing engineers. For example, the Erasmus+ program such as the Erasmus Mundus Joint Master in Sustainable Mineral and Metal Processing Engineering, EMJM PROMISE, is the first program focusing on mineral processing specialization. Addressing the shortage of mineral processing engineers requires educational reforms, efforts to attract young professionals, and investment in modernizing the industry's image to emphasize sustainability and technological innovation and cooperation.

Resumen

This paper assesses the compositions of the Lithium-rich minerals and the quantity of extractable Lithium oxide in the minerals. The x-ray diffraction (XRD) shows 17% - 34% of spodumene and 9% to 30% of lepidiolite. Similarly, atomic absorption microscopy (AAS) indicates that the Lithium-rich minerals contain 0.820% - 3.051% and 0.040 - 2.395% of Lithium oxide (Li2O). Further results confirm the presence of Lithium-rich minerals in Nigeria, and a high quantity of Lithium-rich minerals suggests that high Lithium oxide can be extracted. This information is useful for miners, mining and mineral processing industries, and investors in Lithium for different industrial applications.

Resumen

Seafloor Massive Sulfides (SMSs), which were formed by deposition of precipitates from hydrothermal fluids vented from seafloor, has been expected as one of unconventional mineral resources on deep seafloors in the oceans. The authors have proposed the concept of seafloor mineral processing for SMS mining, where valuable minerals contained in SMS ores are separated on seafloor while gangue minerals are disposed on seafloor in appropriate ways. To confirm the applicability of column flotation, which is one of conventional mineral processing methods, to seafloor mineral processing, the authors carried out experiments simulating column flotation under the pressure conditions corresponding to the water depths down to 1000m in maximum using ore samples containing copper, iron, zinc and lead. In the experiments, formation of fine bubbles suitable to flotation and overflow of froth layer were observed at high pressures. The contents of copper and zinc in the concentrates recovered in the experiments at 1MPa were higher than those in the feed ores while the contents of silicon and calcium in the concentrates were lower than those in the feed ores. These results suggest that column flotation would be applicable to seafloor mineral processing.

Resumen

Abstract Seafloor Massive Sulfides have been expected to be future mineral resources. The grade of valuable metallic elements in ores of Seafloor Massive Sulfides is usually small percentage. If valuable minerals can be extracted from the ores on deep seafloor, the total mining cost can be reduced significantly. The authors proposed Seafloor Mineral Processing, where ores are to be ground into fine particles and separated into concentrates and tailings on seafloor. The Seafloor Mineral Processing system consists of processing units for unit operations such as grinding and separation. To investigate the applicability of flotation, which is a method to separate ore particles by using the difference in wettability of minerals, to the separation unit, measurements of contact angles of sulfide minerals at high pressures were carried out. The results suggested that the contact angles of the minerals would have relationships with pressure in depending on the kind of minerals and solutions. In addition, applying Laser-Induced breakdown Spectroscopy (LIBS), an optical method for elemental analysis, to measurement of metal grade of ore particles handled as slurry in the processing units was also investigated. Signals assigned to copper, zinc, and lead were successfully detected in the spectra obtained from ore particles in slurry flow.

Resumen

This paper concentrates on the application of a biohydrometallurgical method for processing deep-sea mineral resources. Bioleaching technologies developed for terrestrial sulfide minerals now can be applied for metal extraction from deep-sea hydrothermal sulfides. However, little attention has been given to the bioleaching of terrestrial oxide minerals. A potentially attractive bioleaching system using the Fe(III)-reducing bacterium has recently been proposed for manganese crusts and nodules. Experimental results obtained from these systems demonstrate that bioleaching is an economical and environmentally friendly processing avenue to recover valuable metals from deep-sea mineral resources.

Resumen

Infrared spectroscopy (IR) is a highly effective method for the analysis of minerals, rocks and ores, capable of solving a whole range of problems when choosing innovative solutions for the technological processing of various types of mineral raw materials. The article considers the main directions of using the infrared spectroscopy method in assessing the technological properties of minerals and their behavior in technological processes: evaluation of the grade (quality) of mineral raw materials; analysis of the behavior of minerals in the technological process with prediction of their technological properties; analysis of changes in the structure and properties of minerals in technological processes; operational analysis of mineral substances at various stages of technological processing. The article illustrates all aspects of the use of infrared spectroscopy at various stages of studying the material composition of mineral raw materials in its enrichment assessment by specific examples of solving problems arising from the technological redistribution of various types of ore and non-metallic minerals.

Resumen

The mining and processing of minerals underpins modern technology and infrastructure. Each year, over 3.3 billion tonnes of metals are produced globally, and most predictions of demand show increasing consumption of metals in the coming decades, including in renewable energy generation, electric vehicles and batteries. The transition of the world’s economies and industries to more sustainable energy and technologies will require more mining and processing of non-renewable mineral resources, with associated positive and negative impacts on the environment and society.
