Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject pyrrhotite.
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
The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed. Literature shows that flotation has not been successful to recover nickel from laterite
The processing plant has a capacity to process at a rate of 2,000t/d and employs conventional crushing, grinding and flotation methods to produce separate nickel and copper concentrates.
sulfide minerals in the flotation tailing might be concentrated with a. wet~ high intensity~ magnetic separator. Then the sulfide richfraction could copper nickel tailing, might find application in the aluminum industry, since it contains about Z9 percent alumina, Al Z03. Although usually termed anor173;
The tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate. Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered.
The effects of configuration of the stirred tank and energy input on the flotation performance of nickel ores were systematically investigated in this paper.
biotechnological process in dealing with nickel bearing flotation tailing, being more attractive than the conventional chemical leaching where just 27.62 % of the nickel content was

The rate constants for nickel flotation were significantly lower than those of copper . This is to be expected in the case of pentlandite which is known to float more slowly than chalcopyrite. This is to be expected in the case of pentlandite which is known to float more slowly than chalcopyrite.
Danafloat 123 is the most selective collector in the Danafloat dithiophosphate range. It has no frothing characteristics. Being a selective reagent Danafloat 123 is useful as a rougher collector producing a high grade first concentrate. For optimum recovery a scavenger collector, e.g. a stronger dithiophosphate or a xanthate in conjunction with Danafloat 123 is used.

a series of floatation cells that separate the desired mineral from other materials. Air injected into the floatation cells, along with foaming The floatation process can separate a desired mineral such as copper, nickel, molybdenum, or zinc from ore. Floatation can separate the desired mineral from
