Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of 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. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals, the ore is crushed and ground to li

Perhaps the most successful direct lead smelting alternative is the Russian Kivcet process. This continuous process uses a vertical flash smelting shaft for first-stage combustion. Some coke is also added in the shaft to form a coke filter that floats on the molten bath, so that slag from this stage is substantially reduced at about 1300 C. Both molten products and gas flow under a dividing ...
