  • Thiourea leaching of a copper-gold ore using statistical

    Discussion This work has adopted a factorial design approach to the assessment of thiourea leaching of the copper-gold ore. Eighteen experiments were used to create a model which describes the leaching of gold on the basis of selected factors. The study showed that acid washing is essential prior to thiourea leaching (Fig. 6).

    The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.
