ABSTRACT
In this article, pre-treatment such as bio-leaching before cyanidation is discussed as an alternative technique to treat refractory gold ores containing pyrite and arsenopyrite. There are two methods of bacterial leaching, namely stirred reactor bio-leaching and bio-heap leach processes. The examples of industrial applications and economics of bacterial leaching are given in detail.
