    Process of Cyanide Gold Extraction

    Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high lime solution prior to cyanidation. It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 0.3 to 0.7%
