Copper Mining and Processing: Processing of Copper Ores ...

The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less …

Copper Ore - an overview | ScienceDirect Topics

The principal copper ore mineral is chalcopyrite (CuFeS2), which is commonly smelted to yield a matte containing ~50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist, 1978).
