Based on Vanadium and Titanium iron concentrate pellets as raw material produced by direct reduction process of coal rotary hearth furnace in an enterprise, the paper studies the impact of magnetic separation process parameters on magnetic separation effect. The results shows that: the use of magnetic separation process can successfully separate metallized pellets, and obtain vanadium titanium micro-alloy iron powder and ti-enriched slag; suitable magnetic separation process parameters are: excitation current of 4A (magnetic field strength 2250Oe), particle size -200 mesh (-74μm), mine concentration of 1:3, iron recovery 92.5% TiO2 recovery up to 55.5%.

Abstract To comprehensively reuse copper ore tailings, the recovery of γ-Fe2O3 from magnetic roasted slag after sulfur release from copper ore tailings followed by magnetic separation is performed. In this work, after analysis of chemical composition and mineralogical phase composition, the effects of parameters in both magnetization roasting and magnetic separation process with respect to roasting temperature, residence time, airflow, particle size distribution, magnetic field intensity, and the ratio of sodium dodecyl sulfonate to roasted slag were investigated. Under optimum parameters, a great number of γ-Fe2O3 is recycled with a grade of 66.86% and a yield rate of 67.21%. Meanwhile, the microstructure, phase transformation and magnetic property of copper ore tailings, roasted slag, and magnetic concentrate are carried out.
