【 摘 要 】

The direct reduction-melting and separation combined process was the metallurgical processing route, where the iron oxide was reduced with pulverized coal at the solid state. Then, the metallic Fe and the slag were melted and separated at high temperature liquid state. The experiments of this direct reduction-melting and separation combined process were conducted with vanadic titanomagnetite, nickel-laterite ores and copper tailings as raw materials. The experimental results demonstrated that the process could contribute to the comprehensive utilization of the low grade complex iron ore, which is suitable for commercialization.
