Electrochemical study of chalcopyrite dissolution in sulfuric, nitric and hydrochloric acid solutions

Electrochemical and surface analyses were carried out to study the leaching of chalcopyrite in acid media, aiming to increase copper extraction from low-grade chalcopyrite ores. Unpublished results include the use of electrochemical impedance spectroscopy (EIS) to characterize the dissolution resist...
