Efficient utilization of nickel rich Chromite Ore Processing …
In the present study, the tailings generated from a chromite ore beneficiary plant in India were investigated through a pyro-metallurgical route. The initial characterization confirmed the presence of nickel (0.5–0.9% Ni) in the ore, which led to the interest in smelting the ore to obtain nickel in the metal.
