Texto completoSmall-scale mining entrepreneurs are confronted with a variety of challenges during both the start-up and growth phase of their businesses not only in South Africa, but all over the world. Most small-scale mining entrepreneurs are not able to take advantage of the opportunities that are available to them. This retards the growth of their businesses. The aim of this study was to investigate the challenges and prospects for small-scale mining entrepreneurs in South Africa, the support structures available to them as well as the factors that could make them successful. The research problem in this study is that the mining sector is biased towards more established companies and against small-scale mining entrepreneurial operations, which marginalises small-scale mining entrepreneurs. Despite being a significant source of revenue for South Africa, the mining sector does not directly benefit the historically disadvantaged people. Notwithstanding government interventions, small-scale mining entrepreneurs face numerous challenges during both the business start-up and growth phase of their businesses with very few prospects of succeeding. This is a qualitative study that uses a series of face-to-face interviews with mining entrepreneurs in South Africa to generate data. Given that small-scale mining entrepreneurs are in most cases part of the informal sector and difficult to locate, a database of small-scale mining entrepreneurs was obtained from Mintek. Initially, 21 small-scale mining entrepreneurs were randomly selected to participate in this study. However, it soon became apparent that ten of them were no longer in business. This meant that the sample was reduced to eleven mining entrepreneurs, located in four provinces: Free State, KZN, Mpumalanga and Limpopo. The findings of this research reveal that small-scale mining entrepreneurs are handicapped by a lack of financial and technical resources, and therefore cannot purchase capital items. It seems that there are good prospects for small-scale mining, particularly in open markets. However, they are unable to exploit these prospects because they lack the necessary finance. Although there are support structures to assist them, they find it difficult to meet the criteria for loans or overdraft facilities from financial institutions. Although these mining entrepreneurs have benefited from the support they have received thus far, they need equipment and commitment to their businesses to remain successful. A series of recommendations are made to guide small-scale mining entrepreneurs already in business, prospective small-scale mining entrepreneurs and other stakeholder’s interested in transforming the industry.

Texto completoOne of the biggest challenges for Mining in the New Millennium is the integration of small-scale mining in the active and sustainable system of exploitation of mineral resources. Small-Scale Mining (SSM) is a mining activity defined by low productivity low capital expenditure and revenues. Artisanal Mining (AM) is just a subset of SSM, characterized by rudimentary mechanization, inefficient recovery, unsafe working conditions and labor exploitation. This thesis intends to answer the following research questions: 1) Can SSM can be sustainable? 2) If so, how can it be evaluated as such? 3) How can sustainable SSM be put into practice? Along the thesis is shown how SSM can be sustainable only coming out of the artisanal dimension. Such a process depends on its own ability to operate efficiently. When operational efficiency is achieved, sustainability comes as a consequence. Through operational efficiency, an operation of SSM comes out of the artisanal condition, it becomes sustainable, and sustainability of surrounding livelihood and environment is strictly consequent. This thesis approaches the issue of SSM in a quantitative and not qualitative way. Basic indicators are individuated specifically to measure the peculiar characteristics of artisanal mines, which differentiate the latter from industrial mines. The purpose of these indicators is the standardization of artisanal mine evaluation on a quantitative basis, an important yet currently unavailable research tool. The analysis of such indicators enables the potential sustainability of an underground artisanal mine to be measured, as well as its upgrade over time towards classification as an industrial small-scale mining unit. It is proposed a new approach for the management of mineral resources and reserves specifically for small-scale mining, in order to upgrade artisanal mines into small-scale industrial mines. The proposed approach to calculate this reserve contains two main concepts: a minimum reserve required for the project start-up and replication to confirm the feasibility of continued operation. The proposed methodology, applied to an actual underground gold mining operation, proved that, in the case analyzed, the reserves required for the small-scale operation are in the order of magnitude of 1/1000 of that required for large-scale mining, when both businesses possess the same level of feasibility. This work shows how a responsible and sustainable form of SSM is possible, achievable and viable, helping the economical development of the area where it operates, and creating positive externalities such as education, capacity building, culture of efficiency and environmental awareness.

Texto completoThe gold mining industry has mainly relied upon the use of a highly polluting chemicals, such as mercury and cyanide, to recover gold from its ores. As environmental legislation has become more stringent in all countries and environmental protection has become the focus of world-wide research, development of environmental sound processes has been favoured. The Coal Gold Agglomeration (CGA) process is such a process which was developed some years ago and has the advantage in that gold is recovered by a procedure which has little or no effect on the environment. The CGA process is based on the hydrophobic characteristics of coal, gold and oil. Gold particles which are substantially free become attached to the coal-oil agglomerates during collision, and eventually penetrate into the agglomerates. The resulting agglomerates are recycled to increase the gold loading, separated from the slurry, burnt, ashed and smelted to produce gold bullion. Laboratory scale batch tests were performed on an artificial/synthetic gold ore, containing fine gold powder. The slurry was contacted with a mixture of coal and oil. i.e. coal-oil agglomerates, after which both the agglomerates and ore were analysed for gold. Operating parameters, such as the mode of contact between the coal-oil phase and the gold containing slurry, contact time of the slurry and the coal-oil phase, means of separating the coal-oil gold agglomerates from the slurry, coal to ore, coal to oil and water to ore ratios, type of oil, effect of collectors and the mineralogy of the ore on the gold recovery were investigated. Results have shown that stirring the coal-oil phase and the slug yielded higher gold loadings than shaking and the traditional rolling bottle technique. BI increasing the time of contact between the coal-oil phase and the gold slurry. the final gold loading in the agglomerates increases, until an equilibrium value is reached. An increase in the amount of coal, together with a decrease in the amount of water used in the slurry, has shown to increase gold recoveries. Furthermore, by varying the concentration and volume of a collector. such as potassium amyl xanthate (PAX) enhanced the settling rate and enabled the effectiveness of separation. Moreover, it was found that the gold loading on the coal-oil phase increased after recycling it. Further tests were performed on a real ore sample and after X-ray Diffraction (XRD) analysis, it was found that certain minerals other than gold was transferred to the coal-oil phase. The theoretical foundation of the CGA process is based on the difference in free energy and was expressed as a function of the interfacial tensions and three-phase contact angles between gold, oil and water, together with the ratio of coal-oil agglomerate to gold particle radii, as the free energy is a measure of the thermodynamic stability and hence, partly a measure of gold recoveries, meaningful predictions as to gold recoveries were made by performing a sensitivity analysis on the variables connected to the free energy, It was, however, found that some operating parameters, which were linked to other factors, such as the maximum gold transfer into coal-oil phase and the separation efficiency of the agglomerates. were vital to be taken into account when predictions as to gold recoveries were made. Therefore, the gold recoveries were found to be a function of the thermodynamic stability as well as the maximum gold transfer into the coal-oil phase and the separation efficiency of the agglomerates, The meaningful information gained by performing the theoretical investigations were applied and linked to gold recoveries, thereby providing useful explanations as to the typical gold recoveries obtained during experimentation. A comparative study on mercury amalgamation was done to evaluate the performance of the CGA process. It was found that the CGA process yielded better gold recoveries than amalgamation, which makes it the better process both in terms of recoveries as well as environmental safety, A further application of the theoretical knowledge was, however, very useful to explain the tendency of the CGA process yielding the better results.

Texto completoThe state of São Paulo is the largest consumer of mineral aggregates in Brazil and one of the largest producers of mineral goods with a production focused mainly on civil construction, agriculture and industry. Taking into account the relevance of mining, the present study aims to characterize how sand and gravel small-scale mining has been contributing to urban planning in metropolitan regions, taking as example, four metropolitan regions in the state of São Paulo and their Integrated Urban Development Plans (IUDP). In this work, an analysis methodology was developed based on the investigation of primary and secondary data sources. The primary data is from the mineral sector of the state of São Paulo, which covers micro, small and medium-mining from 2010 to 2014. Secondary data was obtained from studies concerning the producer and consumer market of the mineral substances chosen for this research. In addition, an analysis regarding aggregate management and public policies was conducted in the Province of Ontario in Canada. Since the study was focused on the state of São Paulo, each of the IUDPs was analyzed and the result is that there is little interaction with the mineral sector and that for mining in the state of São Paulo to be an example of environmental, social and economic responsibility, transparency and information on the activity is necessary, as well as the integration of the relevant actors.

Texto completoIn mining, a large number of uncertainties and risks are associated with geological characterization. The adoption of best practices in mineral exploration results in lower risk and greater effectiveness and efficiency to the operation, adding value to the enterprise. In Brazil, in general, small-scale mining employs little resources for mineral exploration, and the best practices are often ignored. This work addresses the geological risks in mining and how best practices in mineral exploration can be applied in small mining to reduce risks and incorporate value to the project. The application of the CEBIm Priority Matrix in three projects of mineral exploration in small deposits shows how this tool can be utilized in a simple, practical, fast and economical way for assessment of the level of compliance of the mineral exploration program to the best practices, which can indicate the magnitude of geological uncertainty associated with the project.

Texto completoThe small-scale mining (SSM) sector in South Africa has been overshadowed by the wealth generating capacity of the formal mining industry. To address the disparity between the SSM sector and the large formal mining industry, a number of government initiatives have been introduced, the latest being the preparation of the Minerals and Petroleum Resources Development Act 28, which was finalized in October 2002. The Act, which has not yet been implemented, is expected to redress some of the sector's current obstacles. Two case studies conducted in the Northern Cape and North West Provinces, provided the basis for this social impact assessment (SIA). The aim of these studies was to identfy the most serious issues faced by the SSM sector and to assess the likely socio-econiomic impacts of the Act.

Texto completoSouth Africa’s SDFIs have potential to play a critical role in fostering environmental compliance in the mining industry. Their role is particularly important in the small-scale and junior mining sector which is usually shunned by private finance institutions because of high environmental credit risk. Equipped with knowledge and experience of working with clients across different sectors and their potential leadership role in technology transfer, SDFIs can leverage their position in acting as trusted third party environmental regulation enforcers. Financial institutions have long been criticised for showing little interest in environmental impacts of their clients while concentrating on profit maximisation. This study sought to investigate the response by financial institutions to this criticism through evaluating the role of SDFIs in fostering environmental compliance by small-scale and junior mining companies which are generally viewed as having a poor environmental compliance record. Through the twin qualitative research methods of interviews and document analysis, the role of three state-owned development finance institutions in fostering environmental regulation compliance by small-scale mining enterprises in South Africa was evaluated. The study revealed that SDFIs explicitly and implicitly provide a wide range of products and services which help small-scale and junior miners in complying with environmental regulations. The study also found that, while SDFIs are beginning to adopt market-based mechanisms to encourage environmental compliance, they still heavily rely on command and control mechanisms as a way of mitigating environmentally related risks arising from financing mining companies.

Texto completoThis study addresses a principal issue associated with the small-scale mining industry in South Africa, namely mineral rights. Firstly it defines a small-scale mine and its role in the South African economy. It then examines the current mineral rights policy and the conditions under which the current mineral rights policy could be reformed in order to encourage the growth of the small-scale mining sector. Various models and proposals have been examined in an attempt to suggest the most suitable policy in terms of acquisition and distribution of mineral rights, Acquisition of mineral rights remains one of the major obstacles facing small-scale mining companies. The need to change the legal framework surrounding the acquisition of mineral rights is clearly demonstrated in this project report. Simplification of the legal framework would lead to easy access to mineral rights by both large-scale and small-scale, South African and foreign mining companies and remove the traditional complexities associated with the current South African mineral rights policy which tend to sterilise mineral rights. These complexities include subdivision of mineral rights, potential lockup of mineral rights by private companies and individuals and the State. Analysis of methods to rationalise the mineral rights policy have demonstrated that nationalisation and expropriation of mineral rights are counter productive and can not be used as vehicles for access to mineral rights. In order to strengthen the small-scale mining industry changes to the mineral rights have been proposed. A model mineral rights policy framework has been designed to promote small-scale mining. Introduction of a mineral fights tax, taking into consideration the specifics of the South African mining industry, similar to that of Swaziland of 1958 is proposed as one of the ways of discouraging the sterilisation of mineral rights. It introduces a cost element in the locking up of mineral rights by private companies and individuals. It is envisaged that when the cost of holding these mineral rights is greater than the benefits of holding the mineral rights, mineral rights holders would relinquish them thereby allowing access to these mineral rights to other interested parties. The relinquished mineral rights should revert to the State, which in tum should allocate them to qualified mining companies. Due considerations of the unique characteristics of the South African mining industry need to be taken into account when designing any mineral rights policy. Implementation of any such policy should therefore be done with the consensus of the mining industry. Access to State mineral rights is also considered vital. Whilst it is important to provide the small-scale mining sector with access to mineral rights it is recognised that the success of the sector depends many factors, mineral rights among others. A holistic approach that take into all facets of small-scale mining are included in the proposed policy framework for the development of the small-scale mining industry in South Africa.

Texto completoThis mini-dissertation establishes the extent to which small scale artisanal diamond mining impacts on the environment. There has, in the past, been research undertaken specifically on the water related impacts of small scale artisanal diamond mining. This study however, looks at the environment holistically, and gauges the total degradation to the receiving environment. Small scale artisanal diamond mining is considered to be a major contributor to the local economy and improved quality of life for the communities participating in this mining and is being actively supported through the National minerals and mining policies. It is for this reason that it was deemed imperative to understand the nature of the mining and the associated environmental impacts so that the outcome of this report could be used to inform decision makers when considering the licencing and management of artisanal diamond mining operations. In order to achieve the aim of the study, a literature review needed to be conducted focusing on the nature of small scale diamond mining operations, its influence on the social and economic spheres and the known environmental damage induced by such mining activities. However, in order to internalize the impacts, the literature review also drew a comparison with large scale artisanal diamond mining. The problems identified at the four sample sites were evaluated through the OWL Risk Assessment method to gauge the high risks and major impacts. This study showed that water pollution, biodiversity depletion and waste generation were some of the main problems traversing all four sites. In all cases assessed, artisanal diamond mining impacts on the water regime as mining takes place within the riverine environment. This study also underscored the fact that there is very little, if any rehabilitation, of disturbed areas and this impacts upon fitness for use of the receiving environment in the long term. An urgent need exists for monitoring and regulating artisanal diamond mining so as to reduce the impacts to the receiving environment. More enforced regulation will also ensure that the mining operations practice responsibly with due care for the environment coupled to a legal undertaking for rehabilitation of the mining area.

Artisanal and small-scale gold mining (ASGM) has devastating impacts on different parts of the environment and is a source of environmental degradation and contamination. ASGM degrades water resources, contaminate soil, sediments and water and lead to serious land degradation problems. ASGM activities are also associated with socio-economic issues such as child labour, prostitution and health and safety concerns. Insufficient understanding of the environmental and social problems of ASGM in Giyani Greenstone Belt has led to lack of mitigation strategies to reduce such problems. The main aim of this research was to assess and manage the environmental and socio-economic impacts of ASGM in Giyani Greenstone Belt. Remote sensing and GIS and Normalised Differential Vegetation Index were used to assess the effects of mining activities on vegetation cover. Assessment of the effects of ASGM on water, sediments and soil quality involved collection of samples in order to establish their physical and chemical properties. The concentration of toxic and trace metals were determined using Atomic Absorption Spectrometer (AAS) and X-ray Fluorescence (XRF) instruments. The pH meter was used to determine the pH level of the collected samples. Questionnaires, interviews and SPSS were used to assess socio-economic impacts of ASGM. The study culminated in devolvement of NDVI maps and this was used to assess the effects of ASGM on vegetation cover. Results showed that the mining activities in the area had caused extensive environmental degradation due to serious removal of vegetation cover in the site. ASGM had serious effects on soil, water and sediments quality such as environmental contamination by toxic and trace elements. Soil samples were found with high concentration of As, Cr, Cu, Ni, Pb and Zn as compared to the recommended South African Soil Quality and WHO threshold values for plants. It was found that Klein Letaba had high concentration of Ba, La, V, and Ce above the World Soil Averages for plants. Sediments were heavily contaminated with Cr, Ni, Pb, Zn, As and Ba as compared to the recommended standards prescribed by US EPA and WHO. The pH of water, soil and sediments samples collected from both mining sites were found to be strongly alkaline which affects the plants growth as well as aquatic flora and fauna. Socio-economic issues such as child labour, injuries, educational problems, health and safety issues, police disturbance, creation of jobs and income generation were identified at mine sites. ASGM had serious effect on vegetation cover through environmental degradation. ASGM also had serious environmental contamination by toxic and trace elements. ASGM had both positive and negative socio-economic issues at mining site which include employment opportunities, income generation, occupational health and safety, police disturbance and arrests and the use of child labour. Mine site rehabilitation is recommended in this study to reduce environmental degradation. The remediation of contaminated area by concentrated toxic and trace elements should be applied at both mining sites. ASGM should be legalised to enhance positive aspects of the mining such as increase in income generation and creation of more employment opportunities. However, there should be enforcement of mining policies to reduce social and environmental problems.

Texto completoO trabalho dedica-se à Prospecção e Pesquisa Mineral de pegmatitos na região leste de Minas Gerais- Brasil, em contexto de Mineração de Pequena Escala (MPE). Foram investigados 811 depósitos pegmatíticos (minas e garimpos), cadastrados pelo Projeto Leste (1998). Os jazigos descritos foram contextualizados com os Cenários de Geologia e Mineração, do Projeto de Ordenamento Territorial Geomineiro (2008) e, posteriormente, submetidos à análise de critérios de avaliação, que culminaram na seleção de 78 Pegmatitos com Relevante Interesse para Mineração (PRIM’s). A Prospecção Mineral dos pegmatitos foi desenvolvida por meio de ferramentas e técnicas de Geoprocessamento, que deram suporte a etapa de Geologia de Campo. Os métodos investigativos foram aplicados de acordo com a sequência gradativa das fases de prospecção: Estratégica, Tática e Pontual. A cartografia temática, desenvolvida nas duas primeiras fases de prospecção, permitiu identificar tendências e características intrínsecas dos Campos e Distritos Pegmatíticos investigados. A fase de prospecção pontual realizou a interceção dos pegmatitos no terreno, possibilitando a caracterização mineralógica e estrutural dos jazigos, descritos como controle das mineralizações. Para melhor compreensão das massas pegmatíticas em profundidade, foram executados serviços mineiros tradicionais, para abordagem direta das jazidas, através de galerias, cavas, poços e etc. Além desses, foi aplicado ainda o método de prospecção geofísica de Georadar (GPR), com intuito de reconhecer depósitos em subsuperfície e ainda, identificar anomalias geofísicas associadas a zonas de cavidades (bolsadas), produtoras de gemas e minerais de coleção. A Prospecção Mineral permitiu definir blocos de Reservas Minerais orientados ao aproveitamento mineral integrado dos pegmatitos. Os depósitos avaliados como aptos para o desenvolvimento de novos projetos mineiros foram encaminhados para regularização junto ao órgão regulador (DNPM/ANM). O objetivo principal do trabalho foi apresentar um estudo amplo e integrado dos pegmatitos da região com vista o aproveitamento mineral e o fomento mineiro e, por consequência, buscou-se criar uma metodologia de pesquisa replicável a outros depósitos pegmatíticos, inseridos em outras regiões do Brasil. Considerando o crescente valor estratégico atribuído aos recursos pegmatíticos, vislumbra-se a aplicabilidade efetiva para as metodologias e resultados aqui exploradas ,tanto para o Ordenamento Territorial de recursos geológicos, quanto para a atração de novos investimentos no setor mineral, incrementando o desenvolvimento intelectual, social e econômico do Brasil.
The work is dedicated to Prospection and Mineral Research of pegmatites in the eastern region of Minas Gerais, Brazil, in the context of Small Scale Mining (SSM). 811 pegmatitic deposits (mines and diggings), registered by Projeto Leste (1998), were investigated. The deposits described were contextualized with the Geology and Mining Scenarios of the Geomining Territorial Planning Project (2008) and were subsequently subjected to the analysis of evaluation criteria, which culminated in the selection of 78 Pegmatites with Relevant Interest for Mining (PRIM's). The Mineral Prospecting of the pegmatites was developed from tools and techniques of Geoprocessing, that supported the stage of Field Geology. The investigative methods were applied according to the gradual sequence of the phases of exploration: Strategic, Tactical and Specific. The thematic cartography developed in the first two phases of exploration allowed the identifications of trends and intrinsic characteristics in the Fields and Pegmatitic Districts investigated. The specific prospecting phase carried out the interception of the pegmatites on the ground, making possible the mineralogical and structural characterization of the deposits described as mineralization control. For a better understanding of the pegmatitic masses in depth, traditional mining services were performed, for direct approach to the deposits, through galleries, cavas, wells and others. In addition, geophysical prospecting (GPR – Ground Penetrating Radar) was applied to identify subsurface deposits and to identify geophysical anomalies associated with areas of pockets (pockets), producing gems and collection minerals. The Mineral Prospecting allowed to define blocks of Mineral Reserves oriented to the mineral utilization of pegmatites. The deposits assessed as eligible for the development of a new mining project were submitted to regularization with the regulatory body (DNPM / ANM). The main objective of this work was to present a comprehensive and integrated study of the pegmatites of the region with a view to mineral utilization and mineral development and, consequently, sought to create an integrated research methodology replicable to other pegmatitic deposits, inserted in other regions of the region. Brazil. Considering the increasing strategic value attributed to pegmatitic resources, it is possible to see the effective applicability to the methodologies and results explored here, both for the Territorial Ordering of geological resources and for the attraction of new investments in the mineral sector, increasing the intellectual, social development and economic development of Brazil.
