copper nickel bulk flotation

Copper-Nickel ores Danafloat

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

MINNESOTA COPPER-NICKEL RESOURCE PROCESSING MODEL

Bulk flotation of a combined copper-nickel sulfide concenterate is the benefi­ ciation method used in the models. Reagent consumptions are estimated. to be approximately 0.1 lb/mt crude of both xanthate collector and alcohol frother. Fresh water (other than potable) requirements are estimated at 160 gal/mt crude ore. Differential flotation of

Flotation of Nickel-Copper Sulphide Ore: Optimisation of

All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

Studies on recovery of copper, nickel, cobalt and

Oct 01, 2001· Based on our earlier studies on recovery of cobalt from Kalyadi copper ore (Anand Rao, 1997), detailed laboratory studies have been carried out on roasting followed by leaching of the bulk sulfide concentrate obtained by flotation of the Jaduguda ore with the aim to recover the important metals, namely copper, nickel, molybdenum and cobalt. 2.

The Effect of Oxidation on the Flotation Behaviour of

In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.

How to Extract Nickel From Copper-Nickel Sulfide Ore?

4. Bulk-differential flotation process, and recover part of nickel from the flotation tailings. When the floatability of various nickel minerals in ore is very different, the nickel minerals with poor floatability can be recovered from the tailings after the mixed flotation of copper and nickel. Conclusion

West Musgrave Copper and Nickel Project, Australia

Dec 14, 2020· The ore from the deposits will be processed by a grinding circuit comprising two stages of crushing. The plant will use a bulk flotation circuit designed to produce separate copper and nickel concentrates. The circuit will feature bulk rougher flotation, regrinding, a two-stage bulk cleaning process, followed by copper and nickel separation.

Flotation Behavior of Jinchuan High Grade Copper-Nickel

The useful minerals of Jinchuan high-grade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively 1.42% and 1.01%. The content of MgO and SiO2, main gangue components, reached 57.89%. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on
