人造金红石的生产技术及应用研究

Production Technology and Application of Artificial Rutile

人造金红石是一种利用物理/化学方法从钛铁矿中分离出含铁、钙、镁等杂质成分而得到的一种高品位富钛料,是钛产业链关键资源。文章分析归纳了当前盐酸浸出法、硫酸浸出法和还原锈蚀法三种主要生产人造金红石工艺研究现状及人造金红石在下游领域的主要应用情况,最后结合国内相关产业结构的调整规划对人造金红石的未来技术研究及应用前景进行了展望。

Artificial rutile is a high-grade titanium rich material obtained by separating impurities such as iron,calcium,and magnesium from ilmenite using physical/chemical methods.It is a key resource in the titanium industry supply chain.This article analyzes and summarizes the current research status of three main production processes for artificial rutile,namely hydrochloric acid leaching,sulfuric acid leaching,and reductive leaching method,as well as the main applications of artificial rutile in downstream fields.Finally,based on the adjustment plan of relevant domestic industrial structures,the future technological research and application prospects of artificial rutile are forecasted.
