nickel laterite ores to produce ferronickel [5, 6] essentially involves a tradeoff between recovery and grade. The greater the degree of reduction, the greater the recovery of nickel. However, as an increasing quantity of iron (and some more nickel) is reduced to the metallic state, so the nickel grade is diminished.
