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 combinations of fatty acid to recover the cobalt minerals.

Laboratory batch flotation tests were conducted to determine the effect of two types of gasoil-rinkalore mixtures on the flotation response of a copper cobalt oxide ore sample.
A New Application For Flotation Of Oxidized Copper Ore
In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant.

laboratory flotation on an individual basis in order to arrive at an acceptable flotation technique Laboratory flotation testwork was carried out on three different samples from the DRC in attempts to isolate some of the more important variables affecting the flotation of copper and cobalt oxide minerals from these weathered deposits.
Cobalt Beneficiation Technique
The cobalt recovery process has been tested at an operating Missouri lead mine using a continuous flotation unit with very good results. Tests have resulted in development of a flow-sheet that allows for the recovery of 70 pct or more of the cobalt in Missouri lead ore copper concentrates, at grades greater than 3 pct Co or 7 pct combined Ni-Co.
