Process of Cyanide Gold Extraction

Process of Cyanide Gold Extraction. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a highlime solution prior to cyanidation. It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 0.3 to 0.7% chalcopyrite, the remainder being mostly pyrite. The gold content is 0.10 to 0.13 oz.
