Once the cobalt minerals are concentrated, they undergo additional steps to extract cobalt in a usable form. Roasting is a common technique where the ore is heated in the presence of air to remove impurities and convert cobalt sulfides into oxides. Smelting follows, where the roasted ore is melted at high temperatures to separate cobalt from ...

The ore sample used contained 2.03% Cu, 0.15% Co, and 3.73% S. The valuable minerals present were chrysocolla, chalcopyrite, and native copper. The gangue comprised pyrite, carbonate, calcite, and clay minerals. The ore (of a size up to −149 μm) was beneficiated using the sulphidisation and xanthate flotation method.

4000 tons of the ore, producing 55 tons of concentrate assaying 17*7% cobalt. There was little activity in the area after this until 1938 when the Uncle Sam Mining Co. constructed a 75-ton flotation mill. Ho attempt was made to recover the cobalt, and this enterprise also proved unprofitable.

Cobalt production depends on the ore type wherein its occurred. 2.1 Laterite ores In this type of ore, cobalt mostly occurs as a goethite (Fe,Ni,Co)OOH. Most of laterite ores are smelted to produce ferronickel, however cobalt cannot be removed during this process. On the other 700 6 000 2 600 6 300 7 200 63 000

However, if the copper-cobalt ore is over-ground and large amount of fine talc particles (-38 µm) is produced, they will unavoidably be recovered in the water stream and therefore contaminate the concentrate. The understanding of the milling kinetics of copper-cobalt ore can help determining the optimum milling conditions, so as to

mill, as shown in Figure 1. Tests were performed under two conditions: milling in water (reference) and milling in raffinate to measure the in crease in wear rate when milling in raffinate. The material charged in the mill was 1 kg of oxide ore and 428 mL of raffinate or tap water. Fresh slurry was charged for each run.

In the processing of high talc-containing copper–cobalt ore, talc is dealt with by pre-floating it together with quartz and other phyllosilicate minerals (muscovite, micas, chlorite, and serpentine) (Kime et al. 2015; Kime and Kaniki 2017). However, the big challenge comes from the fact that the milling of high talc-containing oxidized copper ...

As-mined ore is typically less than 1/4 meter in diameter. It is ground (wet) to 80% passing 100 μm diameter in a SAG mill and then sent on to atmospheric sulfuric acid/SO 2 (g) leaching. Representative leach reactions are given in Reactions (2.2.27) and (2.2.28).Some Co is trivalent in its mineral form.
