Nickel processing preparation of the metal for use in various products Although it is best known for its use in coinage nickel Ni has become much more important for its many industrial applications which owe their importance to a unique combination of properties Nickel has a relatively high
The concentrate contains 6-12 percent nickel content Magnetic separators can be used in floatation since some nickel-containing sulfides are magnetic The concentrate of nickel obtained is then leached with either sulphuric acid or ammonia dried and smelted similarly like copper
Processing Nickel Ores The non magnetic ore is sent to a series of rougher cleaner flotation cells and produces a 31 copper concentrate 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 Flotation of Nickel
Nickel ore beneficiation can be applied to process copper nickel ore accompanied by Pyrite and other gangue or nickel oxide ore Process Introduction Mixing Flotation Process The mixing flotation process is to separate nickel ore in which copper has lower content than Nickel the mixed concentrate of copper and nickel will smelt into high
