The flotation process is considered one of the most important techniques to separate rare earth minerals from associate minerals and is commonly applied to the beneficiation of rare earth ores. It is worth mentioning that this separation method is used to separate minerals by exploiting the differences in their surface wettability [ 12, 24 ].

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.
