  • Nickel Ores

    Nickel ores are not susceptible to mechanical enrichment. The silicate nickel ores contain cobalt with the Co:Ni ratio of the order of 1:20–1:30. In some deposits, the silicate nickel ores are accompanied by iron-nickel ores with high proportions of iron (50–60 percent) and Ni (1.0–1.5 percent).
