Thermodynamics of the Reduction Roasting of Nickeliferous ...
mum nickel recoveries, separate processing streams were necessary for the low- and high-grade saprolitic laterite ores. Li [12] utilized the F *A *C *T software system to investigate the equilibrium prod-ucts formed as a result of the reduction of both a limonitic ore and a saprolitic ore in a CO/CO 2 atmosphere at various temperatures.
