  • Leaching of copper and zinc from copper converter slag

    May 01, 2012· The following parameters were therefore recommended for chemical leaching of copper converter slag flotation tailings: pulp density 30% (w/v), pH 1.5, 70 °C, initial Fe 3 + concentration 15.7 g/L, no aeration, leaching for 1.5 h. These conditions resulted in solubilization of 81.6 and 37.7% of copper and zinc, respectively, while iron recovery
