efficient gold processing equipment separating gold from the ore

AMIT 145: Lesson 7 Leaching – Mining Mill Operator Training

Cyanidation for gold recovery is used world-wide for various ore types. The process of Cyanidation proceeds in four stages: Preparation of the ore to expose its gold. Dissolution of gold using low strength NaCN solutions (0.05%). Separation of gold-rich liquid from residual solids. Recovery of gold from pregnant solution.
