项目摘要
A new production process of pure TiO2 from ilmenite, which is one of the most important titanium ore, was proposed and demonstrated. The mixture of TiO2 and FeO was reduced to Ti2O3 and Fe by carbon at 1600 degree Celsius. It is confirmed that Ti2O3 dissolved in HCl based acid solution under a hydrogen gas atmosphere. When the solution containing Fe(II) ion and Ti(III) ion was oxidized by air, TiO2 selectively precipitated and the purity of the obtained TiO2 was over 99 mass%. These results indicates that it is possible to produce pure TiO2 from ilmenite with the new process consists of carbothermic reduction of ilmenite to Ti2O3 and metallic Fe, dissolution of the reduced ilmenite in acid solution under a hydrogen gas atmosphere, and selective precipitation of TiO2 by aeration.
提出并论证了一种以钛铁矿为原料生产纯TiO2的新工艺。TiO2和FeO的混合物在1600℃被碳还原成Ti2O3和Fe。在氢气气氛下,Ti2O3在HCl基酸溶液中溶解。当含有Fe(II)离子和Ti(III)离子的溶液被空气氧化时,TiO2选择性沉淀,得到的TiO2纯度大于99%。结果表明,采用碳热还原法将钛铁矿还原为Ti2O3和金属铁,将还原后的钛铁矿溶解于酸性溶液中,并在氢气气氛下进行曝气选择性沉淀,以钛铁矿为原料制备纯TiO2是可行的。
