Abstract:

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

Abstract:

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.

Abstract:

The gold mining fIrm in South Africa is viewed as a normal fIrm producing gold bearing ore but faced with a quality constraint (grade). Grade, however, is never uniformly distributed in a metalliferous deposit and because high grades are mined fIrst, the quality constraint becomes increasingly severe with cumulated production. The fIrm will continue to mine gold bearing ore until it reaches its mining limit where the marginal cost of recovering the gold is equal to the marginal revenue received from that gold and at that point the economic deposit becomes exhausted. Because the mining limit is

Abstract:

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

Abstract:

Gold mining is often associated with positive economic benefits; however, it may also have negative impacts on the environment and human health. It is essential that communities understand the risks and benefits associated with mining, particularly in developing countries where there is often a lack of legislation governing the environmental performance of mining corporations. The perceptions of local people regarding the risks and benefits of mining may differ significantly from those of company representatives, policy makers, and the scientific community. Indeed, public concerns have

This review summarises the factors which control the formation and distribution of surficial gold placer deposits. Regional tectonic and climatic conditions as well as gold source are considered. The characteristics of eluvial, alluvial, marine, glacial and fluvioglacial gold placer deposits are described. Particular attention is paid to the gold grains within these placers. These gold grains have a distinctive morphology and chemical composition which reflect the manner in which they were transported, deposited and concentrated within the placers.

Arsenic contamination of groundwater associated with mining operations is a widespread problem across the globe. The release of arsenic (As) into the environment occurs naturally by oxidation of exposed sulfide minerals.

The Bakyrchik is the largest gold deposit in Kazakhstan and one of the largest in the world. Gold (Au) is dispersed in pyrite and arsenopyrite in the form of microscopic inclusions.

The majority of artisanal miners are involved in micro-mining, but it is believed that the majority of contamination comes from small to large artisanal operations.

Abstract:

The present study provides the results of detailed mapping and analysis of structures encountered in Seguelen pit of Siguiri gold mine, Guinea, where the Siguiri mine is geo-tectonically located in the Baoulé-Mossi domain of Man Shield in West African craton. The gold deposit is hosted in low-grade metamorphic sediments of turbidites sequences which form part of the Lower Proterozoic of Birimian Super group. Three rock formations of Balato, Fatoya and Kintinian underlay the overall pits. The Siguiri gold mine is characterized by the deep weathering profile, developed over the rocks reaching 20

Abstract:

Previous empirical studies show that returns on gold mining equities are positive and statistically significantly related to changes in the price of gold. However, these studies fail to examine operational factors that may provide further explanatory power to gold mining equity returns. Examining quarterly gold mining equity returns, All-In Sustaining Cost and gold production results between 2013 and 2018, I find that there exists a positive and statistically significant relationship between changes in gold mining equity returns and the price of gold and a negative and statistically significan

Abstract:

A method to determine the amount of gravity recoverable gold in an ore sample with a 7.5 cm (3 inch) Knelson Centrifugal Concentrator is presented. The method is based on sequential comminution and recovery steps, the first at 100% $-$841 $ mu$m, the second at approximately 50% $-$74 $ mu$m and the third at final grind (typically 75 to 90% $-$74 $ mu$m). The mass processed depends on the gold grade and particle size, and commonly varies from 25 to 100 kg.<br>The method was used to determine the gravity recoverable gold in nine different ore samples. The grade of these ores ranged from 3 g/t to

Abstract:

This thesis examines the governance of the interface between commercial mining and artisanal and small-scale gold mining in Indonesia. It does so from the under-addressed perspective of artisanal and small-scale gold mining. Using a critical governmentality lens, the research discovered artisanal and small-scale gold miners are neglected because of governmental techniques adopted by global and national bodies to eliminate mercury use. Concurrently, these miners have created alternative knowledge and practices through counter-discourses, conduct and strategies to ensure their mining agenda can
