Production of cobalt from copper-cobalt ores on the

Sep 01, 2020· At Nkana, the copper and cobalt are floated together, then the pH is increased to 9.5 using lime and cyanide is added as a depressant. The cobalt concentrate from this differential flotation typically contains 1.6% Co, 9% Cu and 21% S (Mwakila et al., 2008). This flotation concentrate is treated in the roast-leach-electrowinning plant at Nkana.

Nov 01, 2019· Differential and bulk flotation of mixed sulphide-oxidised Cu–Co ores. Copper complex ores contain profitable amounts of more than one valuable mineral. They are extensively mined in the Zambian Copperbelt. They belong to the more complex Cu deposits in which sulphides occur in a mixture with oxide minerals.

[PDF] NICKEL AND COBALT ORES : FLOTATION Semantic Scholar

Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde

Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasons.

Flotation of mixed oxide sulphide copper-cobalt minerals

Republic of Congo (DRC) from ores containing copper-cobalt oxides or copper-cobalt sulphides. Where oxide and sulphide cobalt-bearing copper minerals occur together, efficient recovery of copper and cobalt is known to be extremely difficult. This study investigates the flotation behaviour of a mixed oxide-sulphide ore where copper is

Jul 18, 2013· A new method for the treatment of Ni–Cu sulphides ores from the Sudbury region by differential flotation is presented. The method exploits the ease of chalcopyrite floatability in complete or virtual absence of collector, but in the presence of sulphur dioxide, an effectivecomplexing agent such as diethylenetriamine (DETA) and a frother.
