Electrowinning Copper Chemistry Tutorial

2019-6-21  Electrowinning can be used to extract the copper from these copper oxide ores. 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. Concentrating : adding water to the powder to create a slurry containing about 15% copper.

The figure below shows how these different types of rock are formed in the lithosphere. Many of the elements that are of interest to us (e.g. gold, iron, copper), are unevenly distributed in the lithosphere. In places where these elements are abundant, it is profitable to extract them (e.g. through mining) for economic purposes.
