    Nickel from lateritic ore is extracted trough extractive metallurgy. It is extracted from its ores trough a conventional roasting method which removes the moisture from the ore. Next the nickel oxide is removed by reduction furnace which also greatly reduces the chemical bound water. Resulting in a 75 pure form of nickel.

    Recovery of valuable metals from a low-grade nickel

    Metal leaching from a low-grade nickel ore was investigated using an ammonium sulfate roasting-water leaching process. The nickel ore was mixed with ammonium sulfate, followed by roasting and finally leaching with water. During the process the effects of the amount of ammonium sulfate, roasting temperature, and roasting time on the leaching recovery of metal elements were analyzed.
