摘　　要：以攀西地区钛铁矿为原料,采用盐酸常压直接浸出法制备高品位人造金红石。结果表明,原矿粒度及盐酸浓度对人造金红石品位影响最大。采用液固比4∶1、盐酸浓度30%、温度95℃的条件,对于球磨4h钛精矿浸出4h可得到TiO2含量94.39%的人造金红石产品,对于未磨原矿浸出10h可得TiO2含量91.78%的人造金红石产品。The synthetic rutile is prepared by directly leaching ilmenite from Panzhihua area with hydrochloric acid. The results show that the grain size of ilmenite ore and the concentration of hydrochloric acid are the most remarkable influencing factors on the TiO2 grade in synthetic rutile. The TiO2 grade of 94.39 % in the synthetic rutile is achieved under the conditions of ilmenite ore 4h grounding, leaching with 30 % HCl solution, 4.1 for liquid/solid ratio at 95℃ for 4h. While for the unground ilmenite ore, it needs 10h to obtain synthetic futile of only 91.38 % TiO2 with the same leaching parameters as for 4h ground ore.
