How Sherritt Refines Nickel

solid copper sulphide. The slurry is passed through a lamella thickener and polish filters to recover the copper sulphide solids. The clarified solution then proceeds to nickel recovery. The solids in the thickener underflow are filtered, washed and sold as feed to a copper smelter. How Sherritt Refines Nickel . Nickel .

nickel sulfide flotation

nickel sulfide flotation

CopperNickel 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 nickelbearing iron sulphides which report to the flotation tails.

Corrosion rates were monitored for over 24 hours, using linear polarization and potential step techniques. The work has shown that coppernickel alloys can corrode quite rapidly in deaerated sea water if these normally passive alloys are made active by the presence of sulfide, or if sulfur is available as an oxidant.
