Jun 15, 2019· Amongst anthropogenic activities, artisanal small-scale gold mining (ASGM) using Hg-amalgamation for gold recovery has been identified as one of the largest contributors to Hg pollution, contaminating the atmosphere, rivers, and people (UNEP, 2018; Wade, 2013).
The Mineral Processing Laboratory provides a wide range of ore beneficiation and metal extraction research services for the mining industry. It is equipped with a unique platform of laboratory bench scale facilities for the development and testing of energy-saving, low-cost crushing, grinding and concentration processes in environmental friendly ways.
Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.

Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.
