Benefits of Agglomeration in an SX-EW Process for Copper Extraction
Solvent extraction electrowinning is a complex process of chemical reactions, but can be simplified into three main steps: Heap Leaching Copper Ore with Agglomeration. Crushed copper ore is first typically processed via heap leaching. An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered.

Copper Mining and Extraction | Copper Mining Processing
The resulting copper matte consisting of Cu 2 S is then roasted to change all sulfides into oxides. 2 Cu 2 S + 3 O 2 ---> 2 Cu 2 O + 2 SO 2. The cuprous oxide is converted to blister copper upon heating: 2 Cu 2 O ---> 4 Cu + O 2. This step exploits the relatively easy reduction of copper oxides to copper metal.
