GOLD: CSIRO recovers gold without using cyanide
A non-toxic method of gold recovery is good news for the precious metals sector. 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 ...

Extraction of gold using cyanide
Au + 2CN- → Au(CN)2- In this form the gold is now soluble. This process is known as leaching. This reaction is normally carried out at a pH of 10-11 as this prevents cyanide ion being converted to hydrogen cyanide which would occur if the pH was lower. Because gold is soluble in this form it can now be separated from the rest of the ore that is
