the process of copper extracted

Extracting copper. Extracting copper.

Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.

The Copper Ore Extraction Process Xinhai

The copper ore leaching process can be divided into roughing, concentration and scavenging of the whole flotation process. Roughing is the first copper ore extraction process, which can separate certain material advanced. Concentration is a re-separation process after the roughing. Scavenging is a re-flotation process on the base of the remaining solid material in the roughing tank.
