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.

Sulfides are minerals that contain sulfur. These minerals are inorganic compounds, which means that they are formed through geological rather than biological processes. These minerals are commonly found in soils with a higher temperature. Oxides are those minerals that contain oxide anions, or oxygen, with ice and quartz being the exceptions.
