12 Flotation of Copper Sulfide Ores different frothers on ores containing montomorillonite and illite clay showed that the frother type had a significant effect on the rate of copper flotation and recovery This effect is illustrated in Figure 129 The HP700 frother gave the best results...
Copper-Nickel ores Pentlandite ((Ni,Fe)S) is the most important nickel sulphide mineral and is often associated with nickel-containing pyrrhotite and chalcopyrite Gangue minerals can include talc and other troublesome silicates which must be dispersed and/or depressed...
One method is froth flotation, in which surfactants bind to ore components, leading to an enrichment of cobalt or Subsequent roasting converts the ores to cobalt sulfate, and the copper and the iron are oxidized to the oxide Leaching with water extracts the sulfate together with the arsenat...
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 This paper describes some early results achieved and experiences gained with these different ores ahead of a more...
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...

Flotation of Nickel-Copper Sulphide Ore: Optimisation of the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore The effect on flotation performance of various parameters such as pH, collector dosage, % solids and depressant dosage at different levels was investigated...
The beneficiation of platinum group metals (PGMs) from pristine (unweathered) sulfide ores has conventionally been conducted through froth flotation, which typically achieves platinum recoveries of over 85% The achieved successes of PGM concentration by flotation from the pristine sulfide ores are largely due to the occurrence of PGMs in close association with base metal sulfide minerals like ....
Jan 17, 2020· Discover all statistics and data on Cobalt now on statista! , froth flotation is commonly used, in which a substance is used to bind to different ore components in order to enrich cobalt or...
Flotation of cobalt sulfide ores can be best achieved at acidic pH (~ 4) with xanthate collectors and at pH of about 75 for oxide ores with nitrosonaphthol chelating reagents, while their ....
Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound or Several methods exist for the separation of cobalt from copper and nickelThey depend on the concentration of cobalt and the exact composition of the used ore...

Nickel and Cobalt Ores: Flotation , (-150+20) μm, was processed by column flotation in three different stages: rougher flotation for magnesium silicates, rougher flotation for sulfides, and ....
If cobalt-bearing minerals are cobalt-rich ores and cobalt sulfide ores with good floatability, it is more economical to recover cobalt concentrate by flotation However, the problem is that cobalt minerals are closely related to other metal minerals and gangue minerals, and their floatability has little difference...
It is very difficult to generalize the performance of different collectors or modifiers in the flotation of massive sulfide ores because both collectors and modifiers perform differently for different ore typ Reagent scheme used in treatment of massive sulfide and refractory copper ore In the treatment of porphyry copper ores, the emphasis ....
Copper-Cobalt or , Two different flotation separation strategies are used Differential flotation sequence: A differential copper-cobalt flotation separation which begins with selective copper flotation by raising the slurry pH to 10 with lime and using a dithiophosphate copper collector The tails produced in the first differential ....
