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.

In this paper, the mineral properties of the lean magnetite in RongTian mine corporation was studied, during which the analysis of the mineral properties, prelimenary separation on the lump mine, two-section grinding, one section fine screening and three-section low intensity magnetic separation process were carried out. The results showed that if the suitable mineral processing flowsheet is adapted, we can achieved such index:concentrate grade of 63.65%, Fe recovery of 47.12% based on the ore grade of 10.05%.. According to the experimental result analysis, most of the iron minerals could be used to support the steel production of LingGang Group.Single magnetic process proved to be an suitable and promising process to conduct the fine particles of lean magnitite.

The composition of Deoxidized Samples of Bayan Obo Oxidized Iron Ore is complex with high content of residual reducing C, Fe phase in the RDP is ferrous metal what is hard and malleable resulting in pessimistic grindability. Gravity-magnetic separation process flow is adopted with C pre-rejecting, stage grinding (-0.074mm -57.18%, -0.074mm -85.66%) and coarse-fine fraction separate treatment base on RDP process characteristic. The final concentrate has 92.02% Fe with 93.27% Fe recovery, 94.18% Fe metallization which may utilize as rough materials for steelmaking and the final tailings has 15.10% REO with 97.15% REO recovery which may utilize as rough materials for REO concentration.
