Steelmaking and Refining | Introduction to Chemistry

Refining. Refining consists of purifying an impure material, in this case a metal. In refining, the final material is usually chemically identical to the original, but purer. There are many different processes for refining, including pyrometallurgical and hydrometallurgical techniques. Wrought Iron

Processing, smelting and refining gold | World Gold Council

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

Pyrometallurgy - Wikipedia

Refining is the removal of impurities from materials by a thermal process. This covers a wide range of processes, involving different kinds of furnace or other plant. The term "refining" can also refer to certain electrolytic processes. Accordingly, some kinds of pyrometallurgical refining are referred to as "fire refining". See also. Blast furnace

Hydrometallurgy - Wikipedia

Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy and molten salt electrometallurgy.
