A process for beneficiating a finely ground ore containing sulfide minerals of copper and nickel by selective flotation to produce a copper concentrate and a coppernickel concentrate comprises pulping the ore with water to form a slurry, conditioning the slurry with an aqueous solution of SO 2 (H 2 SO 3 ) equivalent to from about 2 to about 45 pounds of SO 2 per ton of dry ore for a timeselective flotation of copper and nickel sulfides Strategic Metallurgy have demonstrated differential flotation techniques for Western Australian copper and nickel sulfide ores in saline water Historically, selective flotation of copper from nickel sulfides has been achieved through pH modification; however, this method is rarely efficientIN NICKEL | Metallurgists Perth | Perth | Strategic Metallurgy
A novel copper depressant for selective flotation of
Commonly, the separation of copper sulfide and molybdenite is achieved by means of CuMo bulk flotation, followed by selective flotation of molybdenite from chalcopyrite using copper depressants such as sodium sulfide, sodium hydrosulfide, cyanide and Nokes reagents (Pearse, 2005, Ansari and Pawlik, 2007, Yin et al, 2017a, Yin et al, 2017bSome 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 nickelbearing iron sulphides which report to the flotation tailsCopperNickel ores Danafloat
