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.

Since the beneficiation performance of ore is ultimately governed by mineralogical properties (e.g., phases, texture, liberation, oxidation/alteration) of …

2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.

The final beneficiation flowsheet was proposed as shown in Fig. 9, as no significant achievement was attained by re-concentrating the middlings after the milling. According to this, it can be observed that the coarse and fine middlings were recirculated back to the TBS while the second-stage scavenging spiral was omitted.

Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore.
