American Barrick operates two autoclaves for the processing of refractory gold ores. Because of the mineralogy of the ores, one autoclave is alkaline and the other acidic. The pH of operation has a significant effect on materials of construction, as well as capital and operating costs. The following summary concentrates on the practical and economic aspects of such operations.
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents ...
The leaching parameters were 800 ppm NaCN, DO 16 ppm and pH for a duration of 120 hours. The associated cyanide consumption was kg/t. Gold leaching was not sensitive to cyanide concentration. Reducing the cyanide concentration to 250 ppm resulted in a gold extraction of % with a cyanide consumption of kg/t.
