Nov 01, 2002 · The effect of pyrite, pyrrhotite, chalcopyrite, realgar and arsenopyrite on gold dissolution in cyanide media was investigated. The cyanidation of synthetic gold ores in the presence of various concentrations of sulfides was studied under constant experimental conditions. A mineralogical analysis of the minerals was performed. The leaching kinetics were determined
May 01, 2005 · This paper quantifies the detrimental effects of pyrite and stibnite on gold leaching kinetics. Means to reduce the effect of these minerals by the addition of lead nitrate and oxygen are presented. A significant retarding effect was observed when the pyrite concentration was 20%. A pretreatment with lead nitrate reduced the extent of gold surface coating by Ag, Fe and S. Stibnite, at a
In the beneficiation process, the ore dressing methods used are different due to the different types and properties of gold ore,However, re-election, flotation, amalgamation, cyanidation, and today's resin slurry method, carbon slurry adsorption method, and heap leaching method are commonly used.For some types of ore, a combined gold extraction
