Jan 03, 2018 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.

Abstract. Alluvial gold mining activities in the Peruvian Amazon rainforest are responsible for mercury emissions and deforestation. To understand related environmental impacts, specifically toxicity and climate change, this study uses Life Cycle Assessment methodology. Four predominant extraction systems were selected and modelled and three ...
Both small-scale and artisanal alluvial gold mining methods in Peru use mercury to amalgamate smaller gold particles and increase recovery. It is estimated that in the years 2006 to 2009, 95 of Perus mercury imports were used in ASGM Superintendencia Nacional de Aduanas del Peru . in. USGS, 2007. Alluvial artisanal small-scale gold mining ...
The paper presents a brief history of small scale mining and its present status, alluvial gold processing, including mercury pollution, alluvial gold marketing and the socio-economic problems faced by small miners. 2.
