copper ores an overview ScienceDirect Topics

The principal copper ore mineral is chalcopyrite (CuFeS 2), 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 CuFeSO system at 1 atm SO 2 as a function of temperature (Rosenqvist, 1978).
