摘要
钛铁矿主要含有钛和铁两种元素,约90%的钛矿石用于钛白粉的生产。在硫酸法钛白工艺的基础上,对钛铁矿资源的综合利用进行了综述,认为有3个方向值得关注:利用钛白生产流程中的活性中间品生产新型的高附加值氧化钛功能材料,如介孔氧化钛;利用钛铁矿中的钛和铁元素制备附加值高的含钛、含铁的新材料,如碱式钛铁酸盐;利用副产物硫酸亚铁废渣生产磷酸铁锂这类高附加值的产品。虽然上述产品并不能完全实现钛铁资源的综合利用,但都是高附加值产品,可很好地缓解钛白行业的减排压力。
Ilmenite mainly contains Ti and Fe elements, about 90% of the world＇s total are spent on the production of titanium dioxide.Based on sulfuric acid process for preparing titanium dioxide ,the comprehensive utilization of ilmenite resources was summarized, and it was found that three points were worth paying attention to.The first was taking advantage of active interme- diates in the production process of titanium dioxide to produce new high-value added TiO2functional materials, such as meso- porous Ti02 powder.The second was employing ilmenite to obtain high-value added novel materials, such as basic iron ti- tanates, which included Ti and Fe elements simultaneously.The third was using the by-product ferrous sulfate slag to prepare high-value added products, such as LiFePO4.Though these above ways cannot achieve complete comprehensive utilization of ilmenite, some high-value added products may be manufactured, and the increased profits may be used to offset the environ- ment protection expense of titanium dioxide industry.
