flotation of nickel ores



Flotation of chalcopyrite, pentlandite, pyrrhotite ores,  · The main control measure in the copper/nickel separation circuit is the FLOTATION OF CHALCOPYRITE, PENTLANDITE, PYRRHOTITE ORES 9 lime content of the solution. While it is known that high lime levels are con- ducive to good separation, the lime level is restricted because of the perceived problem that high levels cause in the filtration of the nickel concentrate.nickel flotation processing plant, NICKEL AND COBALT ORES: FLOTATION result in nickel losses into the tailings. This problem can be overcome by using depressants like carboxymethylcellulose CMC and guargum derivatives, although their cost accounts for as much as 60% of the reagent cost incurred in the plant.Nickel: smelting, producing, Nickel: smelting Extraction and purification Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.Upgrading nickel in laterite ores by flotation,  · Flotation has not been successful to recover nickel from laterite ores because of the fine-grain and low grade nickel. Nickel laterite deposits are generally divided into limonite (oxide), nontronite (clay) and saprolite (silicate) zones.BENEFICIATION OF COPPER Et NICKEL ORES, minerals and the nickel was later recovered from the acid liquor after electrolytic refinement of copper. Two other nickeliferous ores not con-taining copper were investigated without success. Table 3.4, at the end of the chapter, summarizes the beneficiation.
