Resumen
This dissertation examines the role of donor-funded international projects to reduce mercury pollution from artisanal and small-scale gold mining (ASM). ASM is the second largest source of anthropogenic global mercury pollution, accounting for roughly 1000tonnes of atmospheric emissions and releases to the environment per annum. The artisanal mining economy involves 10-15 million people across the developing world, and supports 80-100 million people directly and indirectly. In 2003 the Governing Council of the United Nations Environment Program reached consensus that there is sufficient scient

Resumen
Mercury is a well-known toxic element which can be taken up into the human body in different forms, causing particular harm to the nervous system. Despite this fact, it is still used widely in industrial processes, with chlor-alkali electrolysis one of the most extensive pollution sources of mercury. Though most industries today use mercury-free processes, some chlor-alkali factories still use the mercury process, especially in less developed countries. In addition, small-scale gold mining activity remains the largest global mercury consumer and continues to increase the use of mercury given t

Resumen
Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2016.<br>Small-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

Resumen
The general characteristics of gold deposits are reviewed, and a classification of gold deposits based on mineability is proposed. Evaluation, mlnlng and beneficiation methods are briefly discussed. It is concluded that the most viable targets for small-scale companies comprise deposits that require the least pre-production time and expense. Great potential exists for the small-scale reclamation of gold from tailings dumps and abandoned mines in Southern Africa. There is also potential for developing new smallscale gold mines in the Archaean greenstone terranes of the Zimbabwean and Kaapvaal c

Resumen
Um dos maiores desafios para a mineração no Novo Milênio é a integração da Pequena Mineração no sistema ativo e sustentável de exploração dos recursos minerais. A Pequena Mineração (PM) é uma atividade de mineração definida por baixas despesas e receitas de capital e baixa produtividade. A Mineração Artesanal (MA) é apenas um subconjunto de PM, caracterizada pela mecanização rudimentar, recuperação ineficiente, condições operacionais inseguras e exploração do trabalho. Essa tese pretende demonstrar as seguintes questões de pesquisa: 1) A PM pode ser sustentável? 2) Se sim, como pode ser avalia

Resumen
Thesis(MTech (Chem.Eng.Technology))--//Cape Technikon, 1999<br>The 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

Resumen
The current weak state of the platinum market, as well as the large inventory of platinum group metals held by Russia, necessitates that the South African platinum mining industry must carefully evaluate the benefits and disadvantage of small-scale mining of shallow, open castable ore resources. Until the late 1980's, these resources were ignored due to the metallurgical complexities of treating oxidized ore, as well as the mind set that existed within the South African mining industry which militated against open cast mining in the Bushveld. During the latter part of the 1980's and early 1990

Resumen
In considering how women navigate the complexity and gendered aspects of the artisanal mining industry, this study seeks to unpack women's labour at step one of the global supply chain of coltan, in the post-conflict context of eastern Democratic Republic of Congo (DRC). Female miners are largely excluded from mine work by blurry regulatory frameworks, gendered social norms and financial disparities, however they manage to remain active labourers in the artisanal mining industry. Within a broader socio-political context of poverty, political instability and rural livelihoods, women maintain ac
