Mineral Processing. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.

Figure 3 shows a conventional copper (Cu) electrowinning cell, where copper is produced from the PLS. In this process, ionic copper (Cu 2+) in the solution is electrodeposited as metallic copper (Cu o) on the cathode taking two electrons from the circuit, and a counter-reaction has taken place at the anode to hydrolyze the water.

By enhancing the quality of lower-grade raw materials through beneficiation, downstream processes also become more viable. Various production routes are available to transform iron ore into liquid steel, as shown in Figure 1. The selected route depends to a large extent on the quality of the iron ore, energy source and related costs.
