recovery of cobalt from copper ore

recovery of cobalt from copper ore

Cobalt extraction - Wikipedia

The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Iron and lighter impurities float to the surface as solid dross or are expelled from the melt as gas. The remaining liquid is composed of a heavier copper smelt containing approximately 5% cobalt that is processed for its copper and a lighter slagthat is approximately 40% cobalt that is further refined by hydrometallurgical and electr

a Sediment-Hosted Copper–Cobalt Sulphide Ore

Amyl Xanthate (PAX) and a blend of those collectors were evaluated for copper and cobalt recovery. In that study the highest cobalt recovery was 83%, with a grade of 1.88% Co, was obtained using a blend of SIPX and PAX, at a ratio of 3:1 [10]. More recently, it was reported that when using a dithiophosphate collector, 90% of the copper sulphide minerals and 93% of carrollite could be recovered ...

RECOVERY OF COPPER, NICKEL, COBALT AND

It has been discovered that economic recovery of copper, nickel, cobalt and molybdenum is accomplished when the complex ore is roasted with a carbon containing material. The process of this invention comprises roasting a complex ore containing manganese, iron, copper, nickel, molybdenum and cobalt admixed with a carbonaceous material whose carbon content is from about 3 to about 10

cobalt recovery could be obtained at pH values > 4.0. Mintek previously evaluated the problem of simultaneous recovery of Cu, Ni and Co via RIP [5]. During that study it was concluded that a separate copper RIP plant followed by a Ni/Co RIP plant was economically unattractive at the metal prices used for the evaluation and the low Cu grade and hence annual tonnage (400 t/a). Hence, a ...

Cobalt sulfides occasionally occur in lead-zinc deposits in quantities sufficient to justify their recovery. Mineral processing. The most important sulfide sources, the copper-cobalt ores of Congo (Kinshasa) and Zambia, are processed in the conventional manner to produce a copper-cobalt concentrate. This is then treated by flotation to separate a cobalt-rich concentrate for treatment in the ...
