Copper ore is mined for a variety of industrial uses. Copper, ... Metal is extracted from the crushed ore by one of two major methods: smelting or electrolysis. Smelting uses heat to separate the valuable metal from the rest of the ore. Smelting usually requires a reduction agent, or another chemical, to separate metal from its ore. In the earliest smelters, the reduction agent was carbon in ...

The borax process is also an environmentallyfriendly method of extracting gold. Here the goldbearing rock material is placed in a melting crucible and then borax (sodium borate) is added. The borax sinks the melting point of the ore mixture and makes the molten mass more fluid. The low melting point thus enables gold to be extracted using a cost effective, low power heat sources to bring ...
