as preg-robbing ores (naturally occurring carbonaceous material that preferentially absorbs the gold cyanide complex but not the gold thiosulphate complex), it can yield substantially better recovery than cyanide. • The thiosulphate leaching of gold ores has great potential to reduce the impact on the environment compared

native gold from gold-bearing ores. It has been known for more than a century that alkaline solutions of alkali-metal cyanides (e.g., NaCN, KCN) dissolve gold under aerated conditions. The dis-solution of metallic gold is due to the strong complexing capabilities of cya-nide anions combined with the oxidizing properties of the dissolved molecular

Refractory and Non-Refractory Ore. In general, refractory ore is one that is not amenable to gold extraction using cyanide. Refractory ore is undesirable because the methods needed to enable gold extraction are expensive. Non-refractory ore is where cyanide can be used to extract the gold. This is desirable as it means the process will be cheaper.
