cyanidation plant ore

MetallurgyProcessing

Ore Category 3 (1/2" Crushed ore) – low cyanide soluble ratio ores are crushed to a P80 of ". The crushed ore is mixed with soda ash to induce an alkaline 'pre-oxidation' process. After the desired oxidation level has been achieved, the ore will be rinsed sequentially with water and saturated lime solution, and then leached with cyanide to extract gold and silver.
