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

THIOSULPHATE LEACHING AN ALTERNATIVE TO CYANIDATION

CYANIDE IN GOLD PROCESSING THIOSULPHATE LEACHING Thiosulphate leaching is a process that removes gold from gold bearing ores without the use of cyanide. Although not as aggressive a leaching agent as cyanide, thiosulphate offers several technological advantages including its lower toxicity and greater efficiency with gold deposits associated with preg-robbing ores.
