How to Process Gold Ores by Heap Leaching & CarbonChemistry of CyanidationMineralogy of Gold OresGold Leaching Amenability TestingCyanide HeapLeach OperationsCyanide Handling and DisposalRecent Innovations in GoldSilver Recovery from Cyanide Process SolutionsThe basic principle of the cyanidation process is that weak alkaline cyanide solutions have a preferential dissolving action on the gold and silver contained in an ore. The reaction (Eisner’s equation) generally accepted for several decades as representing the dissolution of gold by cyanide solution is 4Au + 8CN + O2 + 2H2O → 4Au(CN)2 + 4 OH…………………………………..(1) Recent research on the mechanism of cyanidation, however,Gold Metallurgy and Leaching ProcessJun 24
