Cyanide Leaching | SGS South Africa

In traditional cyanide leaching, ore is placed in vats or columns. The cyanide solution percolates through the ore and dissolves the gold, which is then removed from the lixiviant by adsorption onto carbon or resins. Grain size, oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery
