Abstract

Abstract

A low-grade ilmenite ore in Yunnan province contains only 5.67% titanium (TiO₂), and most of Ti exists in ilmenite alone, occupying 83.56% of the total TiO₂ in the ore. The rest of 16.44% Ti exists in magnetite and pyroxene in a homogeneous form, and the vein minerals mainly include quartz and chlorite, etc. The beneficiation test for the ilmenite was carried out to seek a reasonable process flow and provide a theoretical basis for the development of this resource, which can make a sufficient use of titanium ore resources. Firstly, the chemical components and mineral compositions of the ore were identified. Then, the process parameters such as grinding fineness, weak magnetic field strength and strong magnetic field strength were studied. On this basis, the combined process of “grinding-weak magnetic separation-strong magnetic separation-strong magnetic separation-graded shaking table re-election-medium ore regrinding and re-election” was proposed. The titanium concentrate containing 45.06% TiO₂ can be finally obtained, with the recovery rate (for the original ore) of 53.73%. The proposed process realizes effective recovery of the target minerals with a well index.
