Abstract: With the reference of previous test results, and combining with the nature of the ore, beneficiation tests for titanium recovery of Panzhihua Baima iron tailings were carried out by the process of classification-one-stage magnetic separation-spiral chute gravity separation-two-stage magnetic separation-flotation. Through the conditioning tests, appropriate technical parameters for each stage were determined. Ultimately, titanium concentrate with TiO2 grade of 46.23% and TiO2 recovery of 29.66% was achieved. Meanwhile, iron and sulfur residues existing in the original iron tailings were comprehensively recovered. The test results can be used as technical basis for building titanium dressing plant in Baima Iron Mine.
