| description | The invention provides a process for smelting Ni, Cr, Co and Fe through an electric furnace from nickel oxide mineral, which essentially comprises the following procedures: taking the weight of crudemineral as reference, adding fluorspar 1-6%, calcined lime 12-18% or limestone 18-24%, coke or peacoke 18-25%; smelting directly in the furnace if the crystallized water in the crude mineral is not more than 20%, and sintering or baking dry first the crude mineral if the crystallized water content is more than 20%, then smelting in the furnace. The invention smelts directly nickel oxide mineral containing Cr and Co by the electric furnace, and can obtain high-grade Ni, Cr, Co and Fe. When smelting from nickel oxide mineral containing 1.5-2.5% Ni, 6-30% Fe, 1-4% Cr, 0.1-0.6% Co and 25-45% Si, the invention can obtain Ni, Cr, Co and Fe containing 6-25% Ni, 44-87% Fe, 5-25% Cr, 1-2% Co, 0.5-1.8% C and 0.8-1.8% Si. The invention is of simple process, high yield and is suitable for industrialized production, consumes 6 |
