The Processing of Low Grade Nickel Ore from South East

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

High Temperature Pressure Oxidation of a Low-Grade

High temperature pressure oxidation of a low-grade nickel concentrate was examined to demonstrate the potential benefits and shortcomings of this approach. The high iron sulfide content ensured that acid generation was much greater than for higher grade concentrates. This results in the formation of basic iron sulfate phases and a significant amount of sulfuric acid.
