A critical review of the passivation and semiconductor mechanisms of chalcopyrite leaching
GM O'Connor, JJ Eksteen - Minerals Engineering, 2020 - Elsevier
The idea that there is a consensus in the field of hydrometallurgy that chalcopyrite leaching
is hindered by a passivation layer is challenged in this review. Not all studies of chalcopyrite …
