Sulfation roasting, a common activation technique, is a potential method for cleaner production of nickel from complex low-grade ores. In this study, nickel oxide–sulfide mixed ore concentrate was roasted with the addition of ammonium sulfate under a static air atmosphere, and the roasted products were leached by water, in order to evaluate the extraction of metals.
After that, nickel concentrate (containing 6–20% Ni) can be collected. The enriched concentrate contains fuel composition in the form of iron sulfide, which can reduce the energy consumption of smelting and facilitate the comprehensive utilization of resources. ... According to the characteristics of nickel ore resources in China, the ...
