The deposit of nickel ore in Indonesia is very abundant. High grade ore has been processed to produce ferronickel, but low grade nickel ore is still left as by product without being processed. This kind of ore has been attempted to be processed through atmospheric leaching and carbon reduction, separately. In atmospheric leaching process, it is found that iron and nickel can be separated from ...
