Cobalt - Wikipedia

Common oxidation states of cobalt include +2 and +3, although compounds with oxidation states ranging from −3 to +5 are also known. A common oxidation state for simple compounds is +2 (cobalt (II)). These salts form the pink-colored metal aquo complex [Co (H 2O) 6]2+ in water. Addition of chloride gives the intensely blue [CoCl 4]2− . [3]

Broken Hill Cobalt Project, New South Wales, Australia

The Broken Hill cobalt project area covers approximately 63km 2 in western New South Wales, Australia. It comprises three major cobaltiferous pyrite deposits namely, Railway, Big Hill and Pyrite Hill. The project site lies approximately 500km by road from Adelaide and approximately 400km by rail from the Port Pirie in the Spencer Gulf.

A new technique, called precipitate flotation of the second kind, in which no surfactant is used to float precipitates, is described. Nickel is completely removed from 1.5 × 10 −5 m-NiCl 2 solutions in 3 minutes using a tenfold excess of nioxime. Flotation improves with increasing temperature between 21° and 40° if the pH is in the range 8-11.

Palladium is completely removed from 5 × 10 −5 M‐PdCl 2 solutions using the new technique of precipitate flotation of the second kind, in which no surfactant is used to float precipitates. Recoveries were best at pH 1-2 and were not markedly dependent on temperature. Increase in ionic strength had no deleterious effect, unlike conventional precipitate flotation.
