separation of nickel from nickel ore grinding

nickel processing - Extraction and refining | Britannica

The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

The nickel laterite ore was initially ground using a vibration grinding machine (XZM-100). The ground nickel laterite ore was screened using a sieve to obtain particles with sizes smaller than 0.25 mm. These were then formed into pellets with sizes of 0.25-0.38 mm to ensure good breathability and reducibility. 2.3 Reduction process
