The leaching and adsorption behaviour of gold ores

Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface. A variable order empirical model of the Mintek form was used to describe leaching, while adsorption was modelled using the film-transfer model. A model of this form was also used for preg­

How to Process Gold Ores by Heap Leaching Carbon ...

Chemistry of CyanidationMineralogy of Gold OresGold Leaching Amenability TestingCyanide Heap-Leach OperationsCyanide Handling and DisposalRecent Innovations in Gold-Silver 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, indicates this reaction proceeds in two stages. Most of the gold dissolves by t
