copper nickel flotation

Copper-NickelOreFlotationProcess: A basic principle ofcopper-sulfidenickelore process is that it is better to let the coppers assimilate into thenickelore. Because it is easier to recovery cooper from thenickelconcentrate. The process has a best advantage-get thecopperconcentrate that has a lownickel…

These are often associated withcopperminerals and pyrite and pyrrhotite iron sulphides. Two differentflotationseparation strategies are used. Differentialflotationsequence: A differentialcopper-cobaltflotationseparation which begins with selectivecopper flotationby raising the slurry pH to 10 with lime and using a dithiophosphate ...

(6)Copper-cobalt oreCoppermineral and cobalt-containing pyrite and other cobalt minerals. (7) Arsenic sulfidecopperore The ore has a high content of arsenic, which is mainly in the form of arsenopyrite.Flotation...

Nickelprocessing -Nickelprocessing - Extraction and refining: The extraction ofnickelfrom ore follows much the same route ascopper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures innickel...

Acoppermine in South America partnered with Nalco Water to help achieve their operational goals. The goals included improving recovery through theircopper flotationcircuit, increasing productivity, and ultimately reducing the total cost of operations while ensuring a safe production environment.

Sequentialflotationin industrial practice is used in cases where thecopperin the head is much greater thannickel(4–5 times). Some of the processes that have been developed recently and are currently in use in a number of operating plants include nitrogenflotationand the application of high-intensity conditioning (HIC).

Separation of the bulk concentratecopperandnickelminerals is generally accomplished byflotationof thecopperfrom pentlandite andnickel-bearing iron sulphides which report to theflotationtails. Pentlandite and iron sulphides are depressed by raising the …

The effects of grinding on the floatabilities ofcopper-nickelsulfides from Duluth gabbro were investigated. At the same mesh-of-grindcopper,nickel, and cobalt recoveries were higher and residual sulfur in the tailings was lower with autogeneously ground pulps.

The Nova concentrator consists of a differentialflotationcircuit wherebycopperbearing mineral are selectively floated prior tonickel flotation. It is imperative that losses ofcopperto thenickelcircuit, and vice versa, are minimised.

The overall consideration shows that at 15 g/toncoppersulphate dosage,nickelrecovery improved clearly by a maximum of about 6 % without grade compromise.

Only theflotationprocess mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of newcopperin 1963, nearly 400 million tons …
