Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in , nearly million tons of ore had to be handled and treated in .

Danafloat offers good selectivity against pyrite in sulfide flotation and can provide good to excellent flotation response to various copper minerals, including but not exclusively, chalcopyrite, bornite, chalcocite and covellite. Other applications are in the flotation of galena and copper activated sphalerite, tetrahedrite and gold ores. The product can be used in conjunction with.

The present invention relates to the production of a cobalt concentrate from ores containing metal sulfides that employs a flotation separation of the cobalt. Generally the process of this invention comprises grinding ore containing sulfides of lead, zinc, and cobalt and forming a slurry.

Copper-Cobalt ores: Copper-Molybdenum ores: Gold-Pyrite ores: Silver ores: Platinum /5(K). The present research aims at recovering copper and cobalt through reprocessing of tailings from flotation of oxidised ores of copper and cobalt achieved at the Kambove Concentrator (DRC).

It focuses on the determination of the reagents’ dosage that enables obtaining the highest recovery of copper (%) and cobalt (%) through flotation Cited by: Flotation kinetics are derived from Kelsall’s unmodified equation and comprise fast and slow floating fractions and rates of metal and/or mineral and gangue.

Together, these variables define a flotation system, whether in the laboratory, pilot plant or production Size: KB. A lead–gold prefloat prior to the zinc flotation allowed the mine to recover oz of gold inin a concentrate assaying 71 g/t Au. In general, however, the gold grade and the mineralogy do not allow the separation of gold from the zinc at the mine and gold is incorporated within the zinc concentrate, or is left behind with the pyrite Cited by: 4.
