Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and combinations of fatty acid to recover the cobalt minerals.
A combined cobalt/copper/gold concentrate is to be produced from the mine and mill and processed at the CPF through hydrometallurgical processing of cobalt and copper bearing sulphides to produce engineering, and milling equipment including the crushing, ball mill, flotation and filtration circuits, pumps United Kingdom,

#0183;#32;Portable XRay Fluorescence (pXRF) was used to analyse the copper and cobalt content of the individual flotation products. The device used was the Delta Premium Handheld XRF Analyser (Olympus, United Kingdom) in Geochemistry mode. Detection limits for copper and cobalt are 20 PPM for cobalt and 5 PPM for copper (InnovX, 2010).

Cobalt and nickel recovery from waste water. Regularities of cobalt and nickel ions precipitation from diluted solutions, similar with respect to these metals content in miningand smelting operations waste water, areHydrophobic precipitates, formed in this way, may be recovered by flotation in machines with low level of energy dissipation.
The company said the drilling campaign had identified multiple cobalt, copper and gold mineralised trends. Additionally, conventional flotation testwork on ore from Cobalt Ridge managed to recover % cobalt and % copper, which are amenable to simple procession options.

Though the gold recovery methods previously discussed usually catch the coarser particles of sulphides in the ore and thus indirectly recover some of the gold associated with these and other heavy minerals, they are not primarily designed for sulphide recovery. Where a high sulphide recovery is demanded, flotation methods are now in general use, but in the days before flotation was known, a
Excellent float recoveries of 93% cobalt (Co), 93% copper (Cu), and 80% gold (Au) into concentrates. Cobalt Blue Process successfully treated the cobalt concentrate for extraction of 90% Co, 95% Cu with 90% of the Au extracted in two steps: 10% in Cobalt Blue Process followed by 80% in cyanide leach of the Cobalt Blue Process residue.
#0183;#32;Before World War II, the producers agreed that cobalt supply should be controlled but that cobalt prices should be uniform. The main producers then were Belgium, the United Kingdom, Canada, Finland and France. After World War II, the Belgian Congo producers quoted the price and the rest of the producers generally followed it.
