The Metallurgy of Cyanide Gold Leaching An Introduction

Refractory Ores/Solid-Solution Gold In some ores, Au can be locked inside the sulphide mineral matrix of the ore (so called solid solution), and the cost for the energy required to grind and liberate is simply too high to be viable. These are "refractory ores" and require a chemical, not simply physical, process to liberate gold from the

Goldstrike Thiosulfate Case Study AuTec Innovative

In the past, sulfide ore at Goldstrike was processed through autoclaves followed by a conventional carbon-in-leach (CIL) process using cyanide. More complex double refractory ores containing both sulfide and carbon presented a challenge for this process as they could no longer be treated profitably.

Effect of Pretreatment on Leaching Primary Copper Sulfide

The aim of this study was to improve the dissolution of copper sulfide ore composed mainly of chalcopyrite (1.21 wt %) and bornite (0.54 wt %) using a pretreatment before leaching. The effect of the pretreatment on copper sulfide dissolution was investigated using different types of leaching. Three sets of experimental tests were performed (flask, reactor and mini-column).
