2000-9-4 · A rapid flotation method for cobalt and copper separation and enrichment from fresh waters is established. At pH 6.0, ionic strength of 0.02 mol/l, using sodium dodecylsulfate as a foaming reagent, cobalt and copper were separated simultaneously with 10 mg Fe(III) and 3×10 −4 mol hexamethylenedithiocarbamate (HMDTC −) added to 1 l of aqueous solution.

Copper-Cobalt ores - Danafloat

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 ...
