Beneficiation of copper ores based on high-density separation fluidized
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.
