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.

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
