Effect of pH Alkalinity on Gold Leaching
Effect of pH Alkalinity on Gold Leaching

The role pH has in affecting gold leaching rates by cyanide and the functions of calcium hydroxide in cyanidation are as follow 1 For safety and to prevent loss of cyanide by hydrolysis 2 To prevent loss of cyanide by the action of carbon dioxide in the air 3 To decompose bicarbonates in mill water before using it in cyanidation 4 To neutralize acidic compounds such as ferrous salts

Effect of pH on Cyanidation Process Hydrometallurgy

CN is required to leach gold and thus at decreasing pHs the quantity of CN decreases due to the formation of HCN as pointed out above Thus the gold leach reaction can become cyanide limited if the CN concentration gets too low can compensate by having higher cyanide addition but also get higher HCN and hence HCN loss
