Copper ore beneficiation methods. 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.Web

Magnetic separation is used, before or after flotation, to remove the iron-bearing gangue impurities associated with spodumene. The processing flowsheet adopted at Bernic Lake employs a low-intensity magnetic separator for the removal of iron-bearing impurities from the fines fraction [19]. The coarse fraction, on the other hand, is subjected ...Web
