Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit. To quantify recovery is a reasonable idea of the initial ore required to have an economical operation. In this part, a reliable sampling representing the ore is a key aspect.

How the Gold Refining Process Works | Global Bullion

The Refining Process. Refiners start with one of two types of gold: a doré bar or scrap. Doré bars are produced by miners and are about 80 percent pure. Refiners increase the purity by separating the other precious metals and less precious metals that are mined with it. Using induction heating, doré bars and scrap are turned into molten metal.
