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 ...

Mar 11, 2016· Craig, our concept is to produce a pyrite-cobalt concentrate which can then be processed via metallurgical roasting to produce sulphuric acid and electricity (the reaction is exothermic and produces heat to generate steam for power generation). The cobalt is retained in high iron ash residue from which it can be recovered by solvent extraction.
A process is disclosed for the recovery of a metal from a pyrite-bearing material. The process comprises thermally decomposing the pyrite-bearing material so as to produce a material comprising pyrrhotite (FeS). The process also comprises leaching the material comprising pyrrhotite with an acid such that the iron in the pyrrhotite is oxidised to a +3 oxidation state, elemental sulphur is ...

Cobalt processing, preparation of the metal for use in various products.. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close-packed crystal structure.At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12 radioactive isotopes, none of which occurs naturally.

Pyrite pricing is dependent on the Chinese sulfur price, which is turn is a function of fertilizer demand for agriculture and food production. In addition, further value is placed on pyrite as a source of iron (40 - 45% Fe), with pyrite residue typically on-sold to steel manufacturers following the removal of sulfur for sulphuric acid production.
Copper concentrate grades ranged from 24.5 to 34.5 percent copper and averaged 27.6%. Copper concentrate quality is shown to be very good with low levels of penalty elements. Cobalt has been shown to be readily recoverable to a pyrite concentrate with grades of this concentrate in the range of 700 to 4500g/t cobalt.

Pyrite is popular for its crystal habit, hardness, streak, lustre and brittleness. Its composition is of iron disulphide having a pale brass-yellow colour. The name "pyrite" is derived from the Greek words "pyrites lithos," which mean "stone which strikes fire," in allusion to the sparking produced when iron is struck by lump of pyrite.
Nov 14, 2011· Both the Pyrite Hill and Big Hill mineralisation can be upgraded by low-cost gravity and magnetic processing or by flotation to form pyrite concentrate containing about 0.5% cobalt. Metallurgical test work has already confirmed that cobalt metal can be produced from the pyrite concentrate using one of several processing options.
