Gold Mineral Processing Comthickener In Angola

Processing, smelting and refining gold | World

The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.

The leaching and adsorption behaviour of gold ores

There are many non-idealities in gold processing which are becoming increasingly important as simple free-milling oxide ores are depleted. During cyanidation and adsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it
