Production of cobalt from copper-cobalt ores on the

Sep 01, 2020· A specific cobalt flotation circuit is run at KCM’s Nchanga concentrator. The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3% cobalt and 1.3% copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11. The concentrate

Copper-Cobalt ores Danafloat

Copper-Cobalt ores. Various cobalt bearing minerals have economic significance including cobaltite (CoAsS). carrollite (Cu(Co.Ni)2S4), and linnaeite (Co3S4). These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used.

Flotation of mixed oxide sulphide copper-cobalt minerals

Jul 01, 2019· The application of hydroxamate collectors promises to improve the overall performance flotation of copper and cobalt from mixed sulphide-oxide ores. With regards to the problematic carbonate and silicate gangue, reverse flotation to remove these minerals prior to copper-cobalt flotation or the use of depressants may prove useful.

[PDF] NICKEL AND COBALT ORES : FLOTATION Semantic Scholar

Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day

mining froth floatation of cobalt

Froth Flotation is the most widely used method for ore benefaction whereby valuable minerals are separated from other non-valuable minerals by inducing them to gather in and on the surface of a froth layer. Froth flotation is particularly effective in recovering cobalt, nickel and copper minerals from above ground ore stocks and underground ores.

3.2 DRC/Zambian Copper-Cobalt Ores (Oxides & Sulphides) Historically, most of the DRC/Zambian cobalt has been recovered from copper flotation concentrates by a Roast-Leach-Electrowin (RLE) process. This comprised roasting (for the sulphides), sulphuric acid atmospheric leach and direct copper EW; plus impurity

Cobalt and copper recovery from the ancient flotation

The ancient flotation tailings from Lefke, Cyprus, have a potential for non-ferrous metals such as cobalt and copper from more than 9.5 million tons of reserves containing 0.38% Cu, 0.032% Co, and 22.6% Fe. Recovery of cobalt and copper from these tailings can provide great benefits from economic and environmental perspectives.

Flotation of Nickel-Copper Sulphide Ore: Optimisation of

optimum conditions for the flotation of nickel, copper and cobalt from a nickel-copper sulphide ore. The parameters investigated include collector dosage, percentage solids, depressant dosage and pH. The effects of these parameters at three different levels on the recovery of Ni, Cu and Co were investigated using an L 9 Taguchi orthogonal array.
