Gold Mining – The Concentration of the Ore –

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.

Concentration of Gold Ores - a Key to Reducing

2021-3-17  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. It follows therefore, that if mercury is used as a mechanism of concentration, producing concentrates of gold
