Review of Environmental and Health Impacts of

The types of mining studied for this review included both small-scale mining, sometimes called “galamsey”, (illegal mining operations by local people), which is undertaken on a small scale with few tools and equipment, and large-scale mining (legal mining usually operated by foreign companies) conducted on a large scale with heavy machinery.

Environmental impact of mining - Wikipedia

2021-1-11 Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...

The Mercury Problem in Artisanal and Small‐Scale

The Mercury Problem in Artisanal Gold Mining. Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.
