贵州某难选锐钛矿工艺矿物学研究以及可选性探讨

摘要

贵州某锐钛矿嵌布粒度细、伴生关系复杂、含泥量大且原矿品位低,本文在工艺矿物学研究基础上,通过原矿抛尾、原矿抛尾-摇床重选、原矿直接摇床重选试验、浮选试验,探索锐钛矿的可选性.试验研究表明,TiO2难以进行富集.工艺矿物学研究亦表明,该矿嵌布粒度细,含泥量大,属极难选矿石,研究可以对锐钛矿分选技术的发展提供重要的指导意义.%On the basis of process mineralogy study , the separability of an analase ore in Guizhou which is characterized by fine dissemination size, complicated associated relationship, high slime content and low grade in raw ore was explored through the following processes: discarding tailings of raw ore, discarding tailings of raw ore-gravity separation by shaking table, direct gravity separation test of raw ore by shaking table and flotation test. The test research showed that TiO2 was hard to be enriched. The study of process mineralogy also showed that it belongs to the extremely refractory ore due to its fine dissemination size and high slime content. The study offered important instructive significance for the development of separating technology for anatase ore.
