Acid leaching of oxide–sulfide copper ore prior the ...

Oxide–sulfide copper ore was sampled from the ore body Cerovo C1 (south deposit) and used in this study. The chemical composition of the ore sample is pre-sented in Table 1. From Table 1, it can be seen that the high copper concentration is in the sample, as well as the high copper oxide content, while the sulfide copper concentration is lower.
