Abstract:Ilmenite in the west of Panzhihua area is mainly used in coarse-grained and fine-grained classification and separation process, but there are some problems such as complicated process and high energy consumption. In this paper, the properties of coarse-grained and fine-grained ilmenite were analyzed firstly, and then the flotation indexes of coarse-grained and fine-grained ilmenite were analyzed separately. On this basis, the mixed flotation experiment of coarse-grained and fine-grained ilmenite was carried out. The results show that the mixed flotation process of coarse-grained ilmenite is feasible. The research results of this paper provide some reference for simplifying titanium flotation process, reducing production cost and improving ilmenite beneficiation level.
