    An alternative to an autoclave is a roaster, a very high temperature oven that is often used instead of an autoclave if the ore to process contains a large amount of organic carbon. Roasting uses heat and air to burn the organic carbon into fuel and to burn the sulfur off ore, which we heat to 932 to 1,202 degrees F.

    Apr 23, 2010 “If the autoclave discharge is to be leached with cyanide for gold recovery, it is very important to destroy most of the basic iron sulphate in the residue prior to cyanidation. If this is not done, it is very difficult to maintain a pH of 10, which is needed to maintain cyanide in the free cyanide form rather than the toxic, gaseous HCN form.
