Refining of Gold at the Rand Refinery SAIMMRefining metallurgy Wikipedia

Refining of Gold at the Rand Refinery KG Fisher 101 Introduction Since all gold produced in South Africa has been refined at the Rand Refinery Adamson To give the reader a complete picture of gold refining in South Africa the historical development and all operations of the refinery are described in detail in this chapter although some activities cannot strictly be defined In metallurgy refining consists of purifying an impure metal It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material whereas in refining the final material is usually identical chemically to the original one only it is purer
