一、前言 我国攀西地区蕴藏着极丰富的钛铁矿资源,其合理利用将对我国国民经济起重要作用。用稀盐酸加压浸出法制取人造金红石,是攀钛综合利用有效途径之一,但单一浸出工艺,含TiO_2仅达88％左右。为贯彻精料方针,为达到国际市场人造余红石含TiO_2 I. Introduction The Panxi area in our country contains extremely rich ilmenite resources, and its rational utilization will play an important role in the national economy of our country. Preparation of synthetic rutile with dilute hydrochloric acid pressure leaching method is one of the effective ways to comprehensively utilize titanium, however, the single leaching process only contains about 88% TiO 2. In order to implement the principle of fine materials, in order to achieve the international market man-made rutile TiO_2
