Abstract:
AbstractTo improve the direct alloying of manganese ore in steelmaking, the decomposition and carbon reduction of manganese ore was studied using a differential thermal analyzer and resistance furnace. The remaining material after manganese ore decomposition at 1,600 °C was a mixture of 43 % MnO, 40 % MnSiO3 and FeO, and 17 % MnSiO3. The remaining material after the carbon reduction of the manganese ore was a mixture of metal (30.8 % Mn7C3 and 16.1 % FeC3) and slag (2.5 % FeO, 5.1 % SiO2, and 18.8 % MnO). The high-temperature (1,200 ℃) decomposition and reduction of manganese ore produce manganese carbonate, manganese dioxide, and manganese salicylate sesquioxide. However, because it is not easy to decompose the manganese silicate in the manganese ore, the proportion of ore being reduced by carbon is small. Therefore, the increase of the manganese reduction of manganese silicate is critical to the direct alloying of manganese ore. Adding calcium oxide or magnesium oxide to the manganese ore improves the reduction of manganese ore, whereas adding slag from the initial stage or endpoint of the converter process has little effect on the manganese ore reduction.

Abstract:
Rapid reduction roasting of low grade manganese carbonate ore by coal and biomass fuels from Hunan, China was investigated. Magnetic separation behaviors and magnetic properties of raw manganese ore and roasted manganese ores were analyzed. After reduction by coal and biomass fuels, the manganese ores demonstrate a new Mn-Fe oxide phase, showing obvious mixed magnetic behaviors of ferromagnet and paramagnet, and the magnetic susceptibilities of roasting ores rapidly increase to almost two orders of magnitude in comparison of the raw ores. The results show that magnetizing roasting technology could enhanced the magnetic properties of the manganese ores about two orders of magnitude higher than raw manganese ore at low roasting temperature. Thereby, we deduce that the weak magnetic separation combined with high magnetic separation could be adequate for roasted manganese ore to satisfy the requirement of electrolytic manganese industry. Application of biomass in manganese ore roasting process is promising to the effective use of biomass and for decreasing the consumption of fossil fuels in the manganese industry.

Abstract:
Main purpose of this study was to find the optimum conditions to produce a charge material for ferromanganese production or steelmaking with high content of iron and manganese carbides from Denizli-Tavas manganese ore by carbothermic reduction and investigate the effects of temperature, time, amount of active carbon addition and CaO addition on this reduction. The ore was calcined and then mixed with active carbon and CaO. Experiments were performed in a horizontal tube furnace that can be heated up to 1700 º
C with MoSi2 heating elements. After each experiment weight loss data were obtained and converted to percentage reduction. X-Ray, SEM-EDS and chemical analyses were done in order to determine whether or not carbide phases have been obtained, and calculate the composition of the product. Considering the experimental results, the optimum conditions found for reduction of Denizli-Tavas manganese ore were 1250 °
C, 4 hours, 100% of stoichiometric amount of active carbon and 5% CaO addition. Under the optimum conditions 83.85% reduction of calcined ore was obtained.

Abstract:
The Dannemora skarn iron ore deposit is located in the northeastern part of Bergslagen. The deposit has been mined from the 1400’s and stopped in 1992, the mine was reopen in 2012 and it will close in 2015. The Dannemora deposit is hosted by 1.9 Ga old sedimentary and volcanic rocks. The deposit consists of both manganese rich and manganese poor iron ore. The purpose of this study is to investigate the controlling factors for manganese content in both magnetite and surrounding silicate minerals, especially when garnets is present. Also the mineral assemblage and association with different host rocks lithologies shall be investigated. Petrographical and chemical studies indicate the occurrence of both calcic amphibole and Mg-Fe-Mn-Li type amphibole. The calcic amphibole is found in the majority of the samples and is dominant in manganese poor samples where as Mg-Fe-Mn-Li-type amphibole is more abundant in the manganese rich samples. Generally in the manganese rich samples garnet and epidote become more abundant, particularly if the sample is taken close to a volcanic section.
Skarn-järnmalmsfyndigheten i Dannemora är belägen i den nordöstra delen av Bergslagen. Järnmalm och mindre sulfidmineraliseringar har blivit brutna sedan 1400-talet. Gruvan stängde 1992 men togs i produktion igen under 2012. Gruvan stängs återigen under 2015. Fyndigheten är omgiven av 1.9 Ga gamla sedimentära och vulkaniska bergarter. Järnmalmsfyndigheten innehåller både manganrika och manganfattiga järnmalmer. Syftet med denna studie är att undersöka varför fyndigheten har förhöjda halter av mangan. Förändringar av manganhalter och olika värdbergarter borde ge en annorlunda mineralsammansättning i de olika miljöerna. För att svara på dessa frågor skall både mikroskopiska och kemiska undersökningar göras för att bestämma och identifiera olika mineralogiska associationer. Petrografiska och kemiska studier indikerar två olika huvudtyper av amfiboler: kalciumhaltiga amfiboler och Mg-Fe-Mn-Li-amfiboler. Kalciumamfibolerna är generellt mer spridda i proverna medan Mg-Fe-Mn-Li-amfibolerna är mer koncentrerade till de mer manganrika sektionerna. När koncentrationen av mangan är högre blir granater och även epidot och olivin vanligare, speciellt närmare vulkaniska bergarter.

Abstract:
Elevated manganese (Mn) concentrations have been measured in groundwater within the Roanoke River watershed, Virginia. Concentrations of Mn often exceed the secondary drinking water standard. A historic belt of Mn ores, the James River-Roanoke River Manganese District (JRRRMD), occurs in the eastern part of the watershed. The project objectives were to 1) evaluate the formation of the JRRRMD ore deposits and 2) analyze existing groundwater chemistry data to evaluate sources and processes that control groundwater Mn. Analysis of ore minerals, morphologies, and chemistry provides support that the ore deposits are supergene in origin, consistent with previous work. Spatial correlations between Mn ore locations and stream terrace deposits support a model of ore formation in which Mn-oxides were precipitated near discharge zones as anoxic groundwater mixed with oxic groundwater. Terrace deposits present at elevations higher than modern streams suggests that topography has been inverted, allowing ores to be found at higher elevations than what is typically associated with ores formed in discharge zones. Analysis of groundwater chemistry data shows positive correlations between Mn, calcium and bicarbonate concentrations in groundwater, suggesting that carbonate-bearing lithologies are probable sources of Mn to groundwater. Regionally, groundwater flows toward the Roanoke River where the flowpath terminus is marked by elevated Mn. The inverse correlation of Mn with dissolved oxygen suggests that reducing conditions that develop along flowpaths allow for Mn to persist in groundwater. Overall, results suggest that the same processes that allowed for formation of the JRRRM ore deposits continue to occur today.

Abstract:
The Kalahari Manganese Field (KMF) located in the Northern Cape Province about 700km south west of Johannesburg contains 80% of the world manganese ore reserves. Mamatwan Mine is hosted within the low grade Mamatwan type ore and is located in the southernmost tip of the KMF. This mine is an open pit mine which is divided into three benches namely the top cut, middle cut and bottom cut. These three benches are structurally controlled by faults which influence the overall grade of the manganese ore. This study is a follow up work to the previous two studies carried out at Wessels Mine and Mamatwan Mine by (Gutzmer and Beukes) in 1995 and 1996 respectively with regards to alteration processes around fault controlled systems in which they concluded that epithermal fluids caused local reduction and bleaching of ore followed by oxidation and carbonate leaching of manganese ore through ascending oxidized groundwater. Metasomatic activity around fault controlled systems is controlled by three main processes namely redistribution, enrichment and depletion. These processes are determined by mobility/immobility of elements from the fault which are introduced into the pre-existing braunite carbonate rich ore. Elements such as Ca, Mg, Si, Fe, C and Mn interact with pre-existing ore due to temperature, fluid pressure, physico-chemical property of fluid gradient. Structurally, faulting and folding contribute to the movement of elements as one end of the system gets depleted the other end of the system gets enriched and vice versa. To better understand this metasomatic activity, it is crucial to conduct mass balance studies of these elements. Grant (1986) introduced the isocon diagram which is a modification of Gresen’s equation (1967) to ascertain which elements are directly or indirectly related to alteration through enrichment and depletion of Ca, Mg, Si, Fe, C and Mn. As the section approaches from altered to less altered manganese ore the mineral chemistry gradually changes from a manganese rich matrix composed of manganomelane and todorokite to a carbonate rich matrix composed of braunite, dolomite, kutnohorite and Mn-rich calcites.

Abstract:
Main purpose of this study was to investigate the production of high carbon ferromanganese by smelting a manganese ore located in Erzincan. Time, charge basicity, fluorspar addition and coke to ore weight ratio were used as experimental variables. After characterization of the ore, a mixture of 100 grams of uncalcined manganese ore and carefully weighed amounts of coke powder, lime, fluorspar and scrap iron were put into a conical graphite crucible. The graphite crucible with its contents was covered with a graphite lid and placed in an electronically controlled muffle furnace. The furnace was heated to 1600 oC and held at this temperature for a predetermined time and cooled to room temperature. The crucible was taken out of the furnace and the metal and slag phases formed were removed from the crucible by breaking the crucible and carefully weighed. Finally, the metal and slag phase were subjected to chemical analysis. The experimental results show that Erzincan manganese ore can be used in the production of high carbon ferromanganese.

Abstract:
This research focuses on the development of a biological treatment process to enhance silver recovery from a low grade, silver-bearing manganese ore. These manganese oxide ores have been classified as refractory and thereby characterized noncommercial for the recovery and production of silver by conventional methods. A species of Bacillus polymyxa, which was isolated from the Crystal Hill Mine in southern Colorado, facilitated the reductive dissolution of manganese dioxide. Insoluble Mn(IV) was reduced to soluble Mn(II), and silver ions contained within the manganese oxide lattice were released and/or exposed, making them amenable to cyanide extraction. A direct relationship was observed between the biological transformation of Mn(IV) to a lower valence and increased silver recovery following cyanidation. Batch studies, with ore passing minus 10 mesh (0.14 inch diameter), had silver recoveries that were twice the amount extracted by chemical treatment alone over a 120-hour period. However, rates of reductive dissolution diminished significantly as ore particle size increased and specific surface area decreased.

Abstract:
Manganese is a crucial element in the manufacturing of steel, which in turn is an essential material in many industries including construction and transportation. Its use in the steel making process results in increased strength and resistance. Manganese samples are analyzed quantitatively by volumetric titration techniques. These wet chemistry methods are simple, accurate, and are sufficiently detailed for ordinary personnel to follow with ease. The research method used included the investigation of using secondary standard created from the current mining activities to match the matrix and mineralogy. The matrix matching standard has shown that the mineralogical effect and matrix effect can be controlled by creating the ore specific program. The matrix and mineralogical effect are the main sources of errors in wavelength dispersive X-ray fluorescence analysis with pressed powder pellets. No fundamental parameters corrections and empirical coefficient correction were made on the press pellets calibration lines. The fusion method was investigated as a universal method that can produce fused beads retaining all the elements of interest. The calibration lines were developed from certified reference material and the results were accurate, substantiating that the fusion method elimination the mineralogical effect, matrix effect and particle size effects. Fusion and press pellet methods were compared with the traditional wet chemical method and the results shows no significant difference between the methods. The new methods were tested against three proficiency schemes for manganese and the results were satisfactory, the z-score was below ±3 for all the elements. The participants used different methods including traditional wet chemical analysis and Inductive coupled plasma (ICP). The press pellets method has shown a good correlation with a fusion method were certified reference material was used for calibrations. The new methods were validated using different statistical methods. All the validation criteria were satisfactory. The calibration range for all the lines were satisfactory. The Limit of quantification (LOQ) values for Mn, Fe, CaO, SiO2, MgO, Al2O3, and P were very low. The new methods for the analysis are therefore sensitive enough to give good results for the expected concentration ranges of each element. The statistical analysis performed between fusion and press pellets methods has proven that there was no significant difference between the methods. The conclusion made after the validation procedures was that the methods Page | iv developed for the analysis of manganese ore was fit for purpose of the analysis of the elements of interest for the Kalahari manganese ore. The study confirmed that the newly developed press pellets methods can be used to analyse routine production samples based on the ore type or the area. Borates fusion method can be used for geological explorations, consignment and trade samples. The proposed XRF methods can replace the traditional wet chemical analysis which is time-consuming, toxic and labourintensive.

Abstract:
The aim of the project was to establish rate and mechanisms of solid state reduction of manganese ores. The project studied carbothermal reduction of manganese oxide MnO, two Groote Eylandt (Australian) and Wessels (South African) manganese ores in hydrogen, helium and argon atmospheres at temperatures up to 1400C for MnO and 1200C for manganese ores. Experiments were conducted in the fixed bed reactor with on-line off-gas analysis. The major findings are as follows. ?? Rate and degree of reduction of MnO and ores increased with increasing temperature. ?? Reduction of MnO and manganese ores at temperatures up to 1200C was faster in helium than in argon, and much faster in hydrogen than in helium. The difference in MnO reduction in hydrogen and helium decreased with increasing temperature to 1400C. ?? Addition of up to 7 vol% of carbon monoxide to hydrogen had no effect on MnO reduction at 1200C. ?? In the process of carbothermal reduction of ores in hydrogen at 1200C, silica was reduced. ?? Reduction of both GE ores was slower than of Wessels ore. This was attributed to high content of iron oxide in the Wessels ore. ?? Carbon content in the graphite-ore mixture had a strong effect on phases formed in the process of reduction; thus, in the reduction of Wessels ore with 12-16 wt% C, a-Mn and Mn23C6 were formed; when carbon content was above 20 wt%, oxides were reduced to carbide (Mn,Fe)7C3. ?? Kinetic analysis showed that mass transfer of intermediate CO2 from oxide to graphite in carbothermal reduction in inert atmosphere was a contributing factor in the rate control. ?? High rate of reduction of manganese oxide in hydrogen was attributed to formation of methane which facilitated mass transfer of carbon from graphite to oxide. Hydrogen was also directly involved in reduction of manganese ore reducing iron oxides to metallic iron and higher manganese oxides to MnO. Reduction of Wessels and Groote Eyland Premium Fines ores in the solid state is feasible at temperatures up to 1200C; while temperature for solid state reduction of Groote Eyland Premium Sands is limited by 1100C.

Neste trabalho foram efetuados estudos de depressores na flotação de uma amostra de finos de minério sílico-carbonatado de manganês (estocados como rejeito) da Unidade Morro da Mina / RDM, localizada em Conselheiro Lafaiete-MG. Foram realizados testes de microflotação em tudo de Hallimond modificado, curvas de potencial zeta dos minerais puros na presença e ausência de reagentes e ensaios de flotação em bancada com amostra do resíduo do minério deslamado. Os reagentes estudados foram: fluorsilicato de sódio, metasilicato de sódio, amido de milho, dextrina branca e alguns tipos de quebracho (Floatans T0, T1, T5 e M3) utilizando-se oleato de sódio como coletor. A eficiência dos depressores testados na microflotação em relação à seletividade para a separação do quartzo dos minerais de manganês foi: floatan M3 > floatan T1> fluorsilicato de sódio > metassilicato de sódio > amido de milho > floatan T0 > dextrina > floatan T5. Os pontos isoelétricos dos principais minerais de Mn e ganga presentes neste minério foram determinados: rodonita (pH 2,8), rodocrosita (pH 10,5) e quartzo (pH 1,8). O estudo da adsorção que caracteriza a interação dos reagentes com as superfícies dos minerais mostrou ser de caráter específico. Os depressores mais eficientes na flotação em bancada entre os minerais de Mn e de ganga foram: floatan M3, floatan T1 e fluorsilicato de sódio, onde foram obtidos concentrados com teores de Mn, SiO2 e Al2O3 de aproximadamente 30, 17 e 10 %, respectivamente, para os três depressores testados. No entanto, a recuperação metalúrgica de Mn foi de 72,5 % para o floatan M3, 51 % para o floatan T1 e 45,2 % para o fluorsilicato de sódio. Posteriormente, efetuaram-se estudos preliminares de calcinação desse minério deslamado. O mais alto teor de Mn encontrado foi de aproximadamente 30 % com perda de massa de 11,2 % para temperatura de 1000 °C. ____________________________________________________________________________________________________
ABSTRACT: Flotation depressants were studied from silicate-carbonate manganese ore samples (waste) at RDM – Morro da Mina, in Conselheiro Lafaiete – MG, Brazil. Micro-flotation tests were conducted in a modified Hallimond cell, also zeta potential curves for pure minerals in the presence or lack of reagents and bench-scale flotation tests for deslimed ore waste sample. The following reagents were studied: sodium fluorosilicate, waterglass, starch, white dextrin, some quebracho kinds (Floatans T0, T1, T5 e M3) and sodium oleate as a collector. The efficiency of the depressants during the micro-flotation regarding the selection for separation of quartzo from manganese mineral was as it follows: floatan M3> floatan T1> sodium fluorosilicate > waterglass > starch > floatan T0 > dextrin > floatan T5. The isolectric points (pl) of the main ore were also determined as rhodonite (pH 2.8), rhodochrosite (pH 10.5) and quartz (pH 1.8). The adsorption test, characterized by the interaction of reagents and mineral surfaces, indicates its specific nature. The most efficient depressants in bench-scale flotation test among Mn ore and ganga were floatan M3, floatan T1 and sodium fluorosilicate containing Mn, SiO2 and Al2O3 concentrations of approximately 30, 17 and 10%, respectively, for all depressants herein mentioned. However, the metallurgical recovery for Mn was 72,5 % when using floatan M3, 51 % for floatan T1 and 45,2% for sodium fluorosilicate. Furthermore, calcination preliminary studies were conducted and the highest concentration of Mn found was approximately 30%, with an 11.2% weight loss for a 1000°C temperature.

Abstract:
Abstract This paper investigates the economic benefit of incorporating solar-based preheating of Manganese ore before smelting in electric submerged arc furnaces. Manganese ore is smelted to produce Manganese ferroalloy, a key component in steel production. The smelting process is highly energy intensive, with temperatures up to 1600 °C. The paper discusses the developed methodology for determining the configuration of a concentrating solar thermal (CST) plant to produce high temperature process heat. The CST plant is sized to preheat the ore to 600 °C before it enters the smelter — currently ore enters at ambient temperature. The preheating leads to economic and environmental benefits by offering lower cost heat and reducing carbon emissions for the process.

Abstract:
Soils containing inorganic compounds are frequently encountered by transportation agencies during construction within the right-of-way, and they pose a threat to human health and the environment. As a result, construction activities may experience project delays and increased costs associated with management of inorganic compounds containing soils required to meet environmental regulations. Recalcitrance of metal-contaminated soils toward conventional treatment technologies is exacerbated in clay or organic content-rich fine-grained soils with low permeability and high sorption capacity because of increased treatment complexity, cost, and duration. The objective of this study was to develop an accelerated in situ electrochemical treatment approach to extract inorganic compounds from fine-grained soils, with the treatment time comparable to excavation and off-site disposal. Three reactor experiments were conducted on samples collected from two borehole locations from a field site in Illinois that contained arsenic (As)(~7.4 mg/kg) and manganese (Mn)(~700 mg/kg). A combination of hydrogen peroxide (H2O2) and/or citrate buffer solution was used to treat the soils. A low-intensity electrical field was applied to soil samples using a bench-scale reactor that resembles field-scale in situ electrochemical systems. For the treatment using 10% H2O2 and citrate buffer solution, average removal of 23% and 8% were achieved for Mn and As, respectively. With 4% H2O2 and citrate buffer, 39% and 24% removal were achieved for Mn and As; while using only citrate buffer as the electrolyte, 49% and 9% removal were achieved for Mn and As, respectively. All chemical regimes adopted in this study reduced the inorganic compound concentrations to below the maximum allowable concentration for Illinois as specified by the Illinois Environmental Protection Agency. The results from this work indicate that electrochemical systems that leverage low concentrations of hydrogen peroxide and citrate buffer can be effective for remediating soils containing manganese and arsenic.
