Extracting a metal from its ore

usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure state.

An Introduction to the Electrolysis Process

The electric current causes a forced oxidation-reduction reaction. Electrolysis is an integral part of electrometallurgy, and highly pure elements can be produced using this process. Generally, all mining operations require the ore to be beneficiated (treating a raw material to improve its properties).
