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

Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated

A number of sub-options were considered for each flowsheet. Test work showed that high recoveries of copper and silver to flotation concentrate were obtained for both flotation of ore or acid leach residue. Uranium extraction was also 90% for both acid and alkaline leaching. The preferred flowsheet was selected after trade-off studies by DRA.
