Abstract

Aiming at the characteristics of ilmenite ore with a low grade, fine disseminated grain size and containing plenty of mud in Kunming Yunnan, the mineral properties of the ore samples in this area were analyzed and exploratory experiment of mineral processing were researched in this article.The results show that the titanium containing minerals are mainly rutile, the grade of TiO 2 account for 4.66%, and followed by ilmenite ore and a small quantity of titanium magnetite.The grade of 44.01%~45.64%and the comprehensive recovery of 33.93%~42.14%TiO 2 can be obtained using a combined processing, flotation-magnetic separation processing and flotation-magnetic-gravity separation combined processing are more suitable mineral processing direction, it is a reference significant for the real production.
