Gold Metallurgy. These ores, in which the gold is locked into pyrite or arsenopyrite, or present as tellurides, are becoming more important. The Kalgoorlie ores in particular, contain a significant amount of gold tellurides. Thus current studies at Murdoch University on the reactivity of gold tellurides are very pertinent [10].

In this research, the leaching of complex gold ore was studied using cyanide and glycine. In the absence of glycine, the gold dissolution increases from 6.47 to 62.21% with increasing the cyanide concentration from 250 to 4500 g/t. The ore contains sulfide minerals and base metals, such as copper, zinc, and silver, which are high cyanide consumers.
