Impact of alluvial artisanal and small-scale gold mining

Alluvial artisanal small-scale gold mining overview. ASGM is a term broadly used to describe gold mining by individuals, famili es, or groups with minimal mechanization and often in the informal or illegal sector of the market (Hentschel, Hruschka, and Priester, 2002). ASGM is characterized by several

1. ENVIRONMENTAL IMPACTS OF GOLD MINING IN

Gold mining in Penhalonga represents all methods of gold extraction from deep underground mining, to small-scale mining with mines only a few metres deep, through large-scale alluvial mining and the most infamous gold panning. The area therefore is affected by the environmental impacts of each of these mining methods.
