    DescriptionApplicationShipment StorageRisk FactorsCopper extraction techniques refers to the methods for obtaining copper from its ores. This conversion consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.As in all mining operations, the ore must usually be beneficiated (concentrated). To do this, the ore is crushed then it must be roasted to convert sulfides to oxides, which are smelted to produce.

  • Copper Ore Processing Methods

    From an accessory to gravity methods, flotation very rapidly became a major process and finally, from 1923 to 1927, all but eliminated the gravity method in the treatment of low-grade sulfide copper ores. The rapid development of ball-mill grinding must also be attributed to the adoption of the flotation process, since it was the incentive for
