Presentation of copper. 1. Introduction to Copper Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and

The process for extracting copper from copper oxide ores can be summarized as: Mining : digging or blasting to obtain the ore from the surrounding rock. Crushing : mined ore is crushed into very small pieces. Grinding : crushed ore is ground into a powder.

Copper is obtained from a solution containing 25–30 g/l of copper by the SX/EW process. In many aspects, i.e., the mineralogical composition of the charge, the high efficiency of extraction of copper with the minimum ‘attack’ on pyrite and in the pressure leaching conditions, the process is similar to the process developed by the Sherritt company in the 60s.
