Method for obtaining titanium-rich material from reduced mill tailings and its application
By using wet magnetic separation, flotation, and chlorination, impurities are removed from the tailings of reduction-grinding, solving the problems of low titanium grade and high impurities in the tailings. High-grade titanium-rich materials are produced and applied to the production of titanium dioxide and sponge titanium, achieving efficient resource utilization and cost reduction.

Abstract
This invention relates to the field of mineral technology, and more specifically, to a method for obtaining titanium-rich material from reduction grinding tailings and its application. The method includes: subjecting a first slurry containing reduction grinding tailings to wet magnetic separation to obtain wet magnetic separation tailings; preparing a second slurry from the wet magnetic separation tailings, mixing it with flotation reagents, and performing roughing flotation to obtain a rougher concentrate; subjecting the rougher concentrate to a first, second, and third flotation cleansing process sequentially to obtain a third cleaned concentrate; mixing the third cleaned concentrate with a binder to form pellets, reacting the pellets with a reducing agent and chlorine gas, and then washing to remove impurities to obtain titanium-rich material. This method can obtain titanium-rich material with a titanium grade higher than 80%.
