Cadmium Mining- Process

In this process, the metal reaches its boiling point and begins to vaporize. During this vaporization process, at a certain equilibrium temperature, cadmium alone vaporizes and is collected. The collected cadmium vapor is then further purified using the vacuum distillation method. Cadmium produced from this method contains only 0.3% impurities.

Manganese processing | Extraction, Uses & Benefits

manganese processing, preparation of the ore for use in various products.. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal.
