Factors affecting the elution of gold cyanide from

1994年1月1日  The elution of gold cyanide is suppressed by the presence of cations (M n+) through the formation of M n+ (Au (CN) 2−) on the carbon. The horizontal position of the gold peak in an AARL elution profile was found to be a function of the elution of the cations from the carbon bed.

Ion Exchange Resin Technology in Recovery of Precious

2019年2月5日  Elution process of gold loaded resins in thiosulfate leaching is somehow complex because of co-adsorption of copper and other foreign complexes by resin. Hence, depending on elution technique, copper (as major co-adsorbed metal) and gold can be eluted simultaneously or separately, which are known as one or two-step stripping

Metals Free Full-Text Recovery of Gold from Pregnant

In order to solve the competitive adsorption problem of copper with gold on the resins, the replacement of traditional cupric-ammonia catalysis has been proposed . Dowex 21K resin was adopted to recover gold from pregnant thiosulfate solutions with nickel catalysis. In addition, elution process of gold-loaded resins is complex due to the

Gold processing Mining and concentrating Britannica

The most common method is to roast gold-bearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to destroy the interfering sulfides. Oxidation can also be accomplished by the use of high-pressure reactors called autoclaves, in which the minerals in an aqueous slurry are treated at high temperature and pressure with oxygen
