The metal has 12 radioactive isotopes, none of which occurs naturally.

EP1325165A1 - Recovery of nickel and cobalt values from a ...

Historically, most of the DRC/Zambian cobalt has been recovered from copper flotation concentrates by a Roast-Leach-Electrowin (RLE) process. This comprised roasting (for the sulphides), sulphuric acid atmospheric leach and direct copper EW; plus impurity removal and cobalt hydroxide precipitation, often followed by re-leach and cobalt EW.

cobalt recovery by flotation

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 ...

Sep 06, 2019· Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a "speiss", rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.

Copper-Cobalt ores - Danafloat

Addition of hydrogen gas to saturation precipitates cobalt powder with a purity of approximately 99.6%. Recovery from copper-cobalt oxide concentrates. 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.
