Abstract

PURPOSE:To separate and recover Ni and Co contained in powdered low grade Ni- Co oxide ore as halides in high yields by pelletizing the ore together with a halogen compound and a solid reducing agent and heating the pellets in a nonoxidizing atmosphere. CONSTITUTION:Low grade ore contg. Ni and Co oxides such as garnierite is predried to lower the water content to 10-20wt%, and it is pulverized to <=65mesh. This powdered ore is mixed with a halogen compound such as NaCl or CaCl2 by 5-10wt% to the amount of the dry ore and a solid reducing agent such as coke, coal or charcoal having 48-100mesh size by 3-5wt% to the amount of the dry ore, and the mixture is formed into pellets having >=15mm. diameter. The pellets are heated with a nonoxidizing hot gas contg. <=1vol% oxygen to vaporize and extract Ni and Co as halides. The halides are diffused on the surface of the solid reducing agent, reduced, aggregated, and recovered as a metallic Ni-Co magnetic alloy in a high yield.
