The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to …

During copper ore beneficiation, a grinding process is needed, and the grinding process consumes a large amount of energy [[4], [5], [6]]. Before the grinding of copper ore, pre-enrichment decreases the processing amount of grinding and decreases the energy consumption. Thus, it is important to study the enrichment of copper ores.
