The need for large machinery, resource consents, land access, and other permissions means alluvial gold mining does require substantial investment, but still at a small enough scale that the majority of operations on the West …
The recent Chinese involvement in small-scale gold mining in Ghana has received wide publicity and scholarly attention. While the literature has focused on environmental sustainability, political accountability, and institutional reforms, it is yet to examine local adoption of Chinese technology and its impact on Ghana's rural economy.
This paper covers a broad understanding of environmental impacts of alluvial artisanal and small-scale mining with a focus on anthropogenic influencing.
