Gold refining is a set of technological processes for deep multistage purification, with the removal of foreign matter.
Gold mine concentrates, gold-containing scrap, jewelry scrap, and the sludge remaining after electrolytic copper, zinc, nickel, or silver refining are traditionally used as the sources of refined gold.
The Kyshtym Copper Electrolytic Plant produces refined gold from sludge remaining after electrolytic copper refining, and also from scrap raw materials.
The standard gold bars produced by RCC are of high purity and in compliance with national standards. Gold bars of 500g weight and 1000g weight and granulated refined gold are in demand in jewelry and other industries.
In 2017, the Kyshtym Copper Electrolytic Plant produced over 4 tons of pure gold in gold bars.
