Study on the Thermodynamic and Experimental Carbothermic Reduction Nickel Laterite
The overall utilization of magnesium and other metals should be systematically considered during the exploration of deficient nickel laterite.In this paper the thermodynamic analysis of the carbothermic reduction process for extracting metal magnesium from nickel laterite in vacuum was carried out to investigate its . feasibility.The calculation results indicate that it is feasible technically that the carbothermic reduction process for extracting metal magnesium from nickel laterite in vacuum..Under the temperature of 1723K and the pressure between 30100Pa,metal magnesium was obtained. Removal ratio of magnesium was 99.96％ in residues,SiC and FeSi were obtained in residues that supplied vacuum reduction2 as agent.
