Leaching of chalcopyrite concentrate in hydrogen peroxide

Copper extraction from chalcopyrite is directly proportional to hydrogen peroxide concentration, but the extraction decreases at temperatures above 60C. The maximum copper extraction was obtained with the following conditions without stirring 240 min of leaching time, 3.0 M hydrogen peroxide concentration, 40C leaching temperature and 53

Kinetics of pyrite, pyrrhotite, and chalcopyrite

Chalcopyrite (bio)leaching processes include complex oxidationreduction reactions such as the oxidation of minerals, iron, and sulfur, and the hydrolysis of ferric iron. The pH behavior in chalcopyrite leaching solutions may be a result of a combined effect of these reactions.

In particular, the strength of chalcopyrite oxidation is in the order of aqueous solution, acidic solution and acidic solution with sodium chloride. Moreover, the introduction of copper (IT) chloride or ferric chloride into the acidic leaching system can greatly strengthen the direct oxidation and electrochemical dissolution of chalcopyrite.
