Summary of Gold Extraction Process

Cyanidation Gold Extraction Process PrincipleCyanidation Gold Extraction Process FlowCyanidation Gold Extraction Process CharacteristicsCyanidation Gold Extraction Process CaseCyanidation gold extraction processis a method in which gold is extracted from gold-bearing ores using aqueous solution of cyanide as solvent, and then gold is extracted from gold-bearing leaching solution. It includes cyanide leaching process and deposition gold extraction process. First, gold in the gold-bearing ore reacts with cyanide to form a complex into the solution, and then the gold is removed from the solution to metal by a displacement reaction using reactive metal such as zinc. The reaction equation is…

Gold Smelting & Metal Melting Equipment

Ore-dressing low-grade ores to obtain high-grade concentrate, rather than direct-smelting low-grade ores, involves less capital outlay and lower operational costs. However, recovery of iron by a concentrator is rarely as effective as by a furnace, and an additional loss of iron will be taken when concentrates are smelted. Electric furnaces can smelt soft or fine ores and utilize low-grade ...
