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.
Small to medium scale mining equipment for the recovery of gold, chrome, tin, tantalite and more. We are based in South Africa, but our mineral processing plants are supplied globally.
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.
Jun 25, 2019 Small-scale gold mining. Global mercury pollution affects millions of poor people in Southeast Asia, Africa, Central and South America who, in order to provide a livelihood, resort to gold mining using primitive equipment and low-tech approaches.
Global Mining Equipment (GME) provides gold mining equipment that has been designed and built by miners for miners. Rigorous field testing in various countries and climates allows us to tailor designs and specifications for the small (1 ton per hour) to medium scale operations (10+ tons per hour).

Gold alloys with mercury to form an amalgam from which the gold can subsequently be separated by evaporating the mercury. The simplicity of the technique, low investment costs and its comparatively high gold recovery rate has made the mercury amalgam method an integral part of the artisanal and small scale gold mining operations.
Because we have so many innovative, active gold dredgers and small-scale miners on the Klamath River, I don’t recall exactly who came up with the original idea of using a Le’ Trap sluice for final cleanup. When I first heard of it, I had reservations. We have been improving the fine gold recovery on our dredges for years.
Nov 09, 2018 But how does this relate to a small-scale miner? Low-Grade Gold Deposits for the Small-Scale Miner . The Gold Rush boys are working ground that most of us would consider low-grade, but by processing tons and tons of material through massive mining equipment they are still able to recover lots and lots of gold.

Apr 14, 2015 Recovery is a process of eliminating non-gold products from gold. Gravity methods rely on separation based on mass. The particles must have nearly equal size and different mass to be separated. There is a limit to the process of screening to smaller and smaller particle sizes during the recovery of gold.
