Copper Refining Beneficiation Plant Process
In the world, among the total amount of produced copper, about 90% is recovered from the ore containing sulphidic minerals. The main method of beneficiation is flotation, while flotation enrichment flowsheets are relatively simple. In most cases, the particle size of the ore directed to beneficiation is coarse, flotation time is short and circuits of middlings are simple. The concentrates of rougher flotation to are usually reground to liberate copper sulphides from other easy-floating minerals such as pyrite.
Copper ores, although generally contain small amount of copper below 1%, belong to easy-to-float ores, and the obtained concentrates are about 30% of Cu. Technological flowsheets for porphyry copper ores are simple. It includes the following circuits:
ore preparation for flotation
flotation in the milling circuit – rougher flotation
classification and regrinding of rougher flotation concentrate
cleaning flotation with the outlet of the second component of the final tailings from the I
cleaning flotation.
Copper Ore Beneficiation Process Plant Capacity: 5-1500tons
