包头矿稀土藏量很大。包钢在选铁精矿的同时,每年可产出低品位稀土精矿(RxOy20％左右)××万吨。此种精矿将取代目前矿山单独开采的富稀土矿中的贫矿(RxOy8％左右)作为冶炼稀土合金的原料,这给稀土合金生产开辟了丰富的原料来源,但也提出了选择合理流程的迫切任务。矿热炉直接冶炼稀土硅铁合金是综合利用包头 Baotou mine rare earth reserves are large. Baotou Iron ore concentrate at the same time, the annual output of low grade rare earth concentrate (RxOy20% or so) × × tons. Such concentrates will replace the lean ore (about 8% RxOy) in the rare earths independently mined in the mine as a raw material for the smelting of rare earth alloys, which opens up a rich source of raw materials for the production of rare earth alloys, but also proposes to select a reasonable process Urgent task. Direct smelting furnace smelting rare earth ferrosilicon alloy is the comprehensive utilization of Baotou
