Commercial mining and processing of these types of ores are currently exercised only in China. The REO assay in this ore is too low, and it lies around 0.05–0.2%. Therefore, ore beneficiation does not have much role in the processing route. As these deposits occur in the weathered profile, so the open-cast mining methods are adopted.

Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.
