中文摘要: 针对攀西地区钛铁矿储量大、品位低、钙镁杂质含量高等特点，提出钛铁矿盐酸多级逆流浸出生产人造金红石新工艺。实现了盐酸常压浸出钛铁矿，降低了初始浸出酸浓度，解决了盐酸再生与循环利用的衔接问题。通过半工业扩大试验，制备的人造金红石TiO2品位大于94%，钛的直收率大于96%，人造金红石的粒度分布满足氯化钛白的要求。
Abstract:According to the characteristics of ilmenite in Panxi area, a new technology of producing artificial rutile from ilmenite by multi-stage countercurrent leaching process with hydrochloric acid was proposed. So, the atmospheric pressure leaching process on ilmenite was achieved and initial leaching acid concentration was reduced. The connection between hydrochloric acid regeneration and cyclic utilization was resolved. Artificial rutile with more than 94% TiO2 content was produced in semi-industrial expansion test, the direct recovery of titanic was over 96%, and the size distribution of artificial rutile was satisfied with the requirement of titanium chloride.
