摘要
A process for separating gold or other precious metals from arsenopyrite or pyrite ores. The ore is treated with an alkaline solution under oxygenated conditions to break up the sulphide matrix. The ore is arranged to have an initial base: sulphide sulphur stoichiometry of between 0.6:1 to 1.0:1 to maximise the solubilisation of gold or other precious metals. The metals are then extracted from the resultant solution.
