Recovery of cobalt and copper through reprocessing of ...

In some cases, tailings may contain copper and cobalt to concentrations that can be economically recovered. 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).

Cobalt - an overview | ScienceDirect Topics

Typical industrial recoveries to the flotation concentrate of cobalt are 90 ± 5%. FIGURE 29.1. Experimental flotation recoveries of nickel and cobalt to concentrate (Kelebek & Tukel, 1999). They are nearly identical, suggesting that cobalt occurs in the same minerals as nickel, mostly in pentlandite. ... It is also used in the plant built ...

A New Process for Cobalt Nickel Separation - Teck

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

Copper-Nickel ores - Danafloat - Home

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

Cobalt - Wikipedia

Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high energy gamma rays. Cobalt is the active center of a group of coenzymes called cobalamins. Vitamin B 12, the best-known example of the type, is an essential vitamin for all ...

This feed is then further refined at the Usoke plant to produce copper cathodes and cobalt salt. The LOM plan shows that within a few years, layers of mixed and then sulphide ore will be reached. Using pyro-metallurgical techniques, sulphide concentrate (from the flotation plant) will be converted to oxides (in the roaster) and treated at the ...

Copper-Cobalt ores - Danafloat - Home

Bulk flotation sequence: Under the bulk flotation process, a bulk Cu-Co flotation concentrate is produced at natural pH with xanthate, dithiophosphate and/or MBT, particularly if the copper mineralization is chalcocite. Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt ...

COBALT PROCESSING DEVELOPMENTS K G Fisher Bateman ...

The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – e.g. the Kolwezi Tailings Project.
