Development of continuous copper matte converting processes creates a strong demand for continuous copper fire refining. Copper refining requires two stages: oxidation with slagging of impurities and sulphur removal, and copper reduction before anode casting. So, the continuous process needs two reactors or one rector with separated zones.

While hydrometallurgy involves using water for the extraction of metals, pyrometallurgy is a heat-based extraction and purification process. As with the water-based process, pyrometallurgy generally involves three steps: Roasting: This refers to the heating of compounds in air and transforming sulfide ores into oxides, creating gas.

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores.
