2021-12-20 · Concentration of Gold Ores – a Key to Reducing Mercury Use in Artisanal and Small Scale Gold Mining. Posted 3rd June 2012 by Kevin Telmer. In artisanal gold mining, mercury is essentially used to concentrate the gold. It does this by bonding with the gold to form a heavy amalgam that is then easily separated from the other minerals.

2020-9-13 · Gold mining – The concentration of the ore Gold is extremely rare. According to geologists, gold is found exclusively in low concentrations in the rock. Gold is even rarer than platinum, although as platinum disperses more regularly into the earth’s crust it is actually more difficult to find platinum deposits worth digging for.

2016-2-29 · Flotation concentration is not effective on coarse gold. The small miners who wish to treat a small tonnage of high grade ore and want a quick return rather than for recoveries near to 100%, probably still find the amalgamation process the best available recovery method. The final product grade depends on the gold ore treated.

In all cases, the Sweetwater Gold Mine was a small individually owned or non-corporate mining operation that had, at best, modest success. A related theme, exemplified by the ore concentration mill, is the evolution of mining technology, and the use of appropriate technology in local non-corporate mining operations.
