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;

GOLD: CSIRO recovers gold without using cyanide

2018-8-29  The CSIRO process replaces cyanide with thiosulphate and a simple flowsheet. Where a conventional cyanide plant to recover gold could costs A$30 million, the non-toxic option would cost as little as A$2.5 million. The low cost alternative could be a game changer for small producers and those looking to “green” their processes.
