Nickel Ore Process, Nickel Ore Mining Equipment
Two samples of lateritic nickel ore have been characterized, one silicate and other oxidized, with nickel grades of 0.60 and 0.28 wt%, respectively. The nickel grades in the oxidized ore vary from 0.16 to 0.26 wt% above 0.037 mm, increasing to 0.41–0.42 wt% below this fraction, where 79 wt% of total nickel is contained.

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.

Because the ores processed vary widely in terms of nickel content and other components, it is natural that both lower and higher reduction degrees are used. Low reductions imply higher slag losses and lower nickel recoveries but also lower power and reductant requirements, whereas higher reductions imply the reverse ( Solar et al., 2008 ).

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.
