The gold refinery focuses on the refining of mine doré (predominantly gold or silver) and old gold scrap in all forms Gold refining methods include wet chemical chlorination (chlorine gas) It is a major refiner of newlyrefined bullion (mainly from mine doré and scrap) delivered to the Shanghai Gold Exchange Its annual manufacture of investment bars, which is dependent on banks or other The smelting step of refining consists of heating the loaded steel wool to melt the gold at 1300°C, with fluxes of silica, feldspar, and borax, to remove impurities Complete separation occurs within 15 hours, at which point the slag is poured off and the molten gold is poured into anode casts and cooled The anodes are approximately 99%Production of Gold Biomedical Engineeringsidered more economical to build a new plant elsewhere A suitable site was available at Rand Refinery, so it was decided to amalgamate the two com panies and in 1966 the new byproducts treatment plant (smelter) was erected alongside the gold refinery The interchange of products between refinery and smelter was greatly facilitated and support functions (administration, laboratory, assay Refining of Gold at the Rand Refinery SAIMMGold Refining Plant We have cemented our presence among the successful Manufacturers and Suppliers of Gold Refining Systems The Gold Refining Systems offered by us are manufactured in compliance with international quality standards Our Refining Systems are designed to yield 9995% pure gold Bulk orders of the Systems are processed by us as Gold Refining Plant/Machine Manufacturer (Aqua Regia Process)The Outotec Gold Refining Plant is the result of more than 30 years’ experience in developing robust and costeffective solutions for precious metals recovery and refining The process has been successfully applied worldwide in installations with annual gold refining capacities from 1 to 50 tons The gold refining process is purely hydrometallurgical, ie an oxidative leaching of gold OUTOTEC GOLD REFINING PLANT
