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.

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.
