    The sulfide ores are beneficiated in flotation cells while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted loaded and transported to the primary crushers. Then the ore is crushed and screened with the fine sulfide ore ( -0.5 mm) going to froth flotation cells for recovery of copper.
