针对我国包头现有高炉—转炉—电炉—电炉提铌工艺存在流程长、成本高、铌损失率大且只能生产含铌１３％～１５％铌铁的情况，提出包头铌资源选冶新思路：用ＣＯ－ＣＯ２混合气体选择性热还原含铌铁矿，９０％以上的铁矿物被还原为金属铁，铌矿物不被还原。磁选分离被还原的金属铁和其他矿物，得到含Ｎｂ２Ｏ５为６．９１％的含铌氧化物，其品位较原矿富集了４倍。然后用盐酸浸洗上述含铌氧化物，９０％以上的铁矿物、磷矿物以及ＣａＯ和ＭｇＯ进入浸液，铌儿乎全部留在浸渣中，得到的浸渣含Ｎｂ２Ｏ５近３０％，Ｎｂ／Ｆｅ＝６，Ｎｂ／Ｐ＝１２，此浸渣可用于冶炼符合工业标准的铌铁（含６０％～６５％Ｎｂ）。
In view of the fact that there is a long process, high cost, high niobium loss rate and only niobium containing niobium from 13% to 15%, the existing blast furnace-converter-electric furnace-electric furnace lifting niobium technology in Baotou proposed a new idea of resource selection and smelting of niobium resources in Baotou : Selective thermal reduction of niobium-bearing iron ore with CO-CO2 gas, over 90% of the iron minerals being reduced to metallic iron, and niobium minerals not being reduced. Magnetic separation of reduced metal iron and other minerals, containing Nb2O5 6.91% of the niobium-containing oxide, the grade enrichment of ore than 4 times. Then, the above niobium-containing oxide, more than 90% of iron minerals, phosphate minerals and CaO and MgO are immersed in the immersion liquid with hydrochloric acid, almost all of the niobium remains in the leached residue, and the obtained leached residue contains nearly 30% Nb / Fe = 6, Nb / P = 12, this residue can be used to smelt industry-standard niobium iron (including 60% ~ 65% Nb).
