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% ...

Cyanide Use in Gold Mining - Earthworks

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;

Cyanide Leaching Chemistry Gold Cyanidation

06/02/2015  The net result is the complication of the chemistry involved in the cyanide process. Compare Cyanide VS Thiosulphate gold Leaching. No two ores are exactly alike. Therefore, it is practically impossible to predict how an ore will act during cyanidation, although broad generalizations can sometimes be made. In general, therefore, every ore presents its own problems in cyanidation.
