Coarse-particle flotation applied to copper sulfide ores

The largest source of copper supply worldwide comes from copper produced through flotation processes. It is estimated that more than 82% of primary copper production comes from concentration by flotation processes. In Peru, the latest mining megaprojects have been concentrator plants (Cerro Verde, Las Bambas, Constancia, Antapaccay, and so on).

Copper-Molybdenum ores

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.

Recovery of Copper from Ammoniacal Leachates by Ion Flotation

 · In this paper, ion flotation was applied to separate copper from ammoniacal leachates of microwave-roasted sulfidic tailings samples. The sulfidic tailings were first roasted at 550 °C for 60 min, for the oxidation of sulfide minerals to more easily soluble sulfates using microwave-assisted irradiation as heating source.

Water Consumption at Copper Mines in Arizona

During flotation there is an excess of water and the medium is alkaline (pH 10 or 11). This is accomplished by adding a reagent like lime to increase the pH from 7 (natural water) to 10 or 11. The resulting product contains about 20% to 40% copper, depending on the minerals involved. The flotation …
