the invention discloses a mineral separation method for vanadium-titanium magnetite ores. the mineral separation method comprises the following steps of: conveying raw vanadium-titanium magnetite ores to a primary grinding stage; conveying the crushed vanadium-titanium magnetite ores to a primary swirler for classification; conveying deposited sand of the primary swirler to a magnetic
Cn102580843a-mineral separation method for vanadium
vanadium occurs in magnetite disseminated in gabbro along with ilmenite which contains most of the titanium. magnetite and ilmenite are separated from the host gabbro by crushing and grinding to p80 45 microns (0.045mm) by the low intensity magnetic separation (lims) technique.
Influence of microwave treatment on grinding and
The effect of microwave treatment on the grinding and dissociation characteristics of vanadium titano-magnetite (vtm) ore were investigated using scanning electron microscopy (sem), nitrogen absorption measurements, particle size distribution measurements, x-ray diffraction (xrd) analysis, fourier transform infrared (ft-ir) spectroscopic analysis, and magnetic separation.
apr 01, 2020 1. introduction. vanadium titano-magnetite (vtm) is a polymetallic symbiotic iron ore primarily containing iron, vanadium, and titanium. iron minerals and titanium-bearing minerals coexist closely, primarily in the form of the strongly magnetic titanium magnetite and weakly magnetic ilmenite; however, vanadium-bearing minerals are mostly isomorphic to titanium magnetite.

the research is of significance not only for the transformation of resource advantage to economic advantage, but also for the sustained rapid and sound development of our national economy.in this paper, we have done with the vanadium-titanium magnetite of china’s inner mongolia xiaohongshan on the basis of thermodynamics.
this paper studies the grinding behaviour of vanadium-titanium magnetite concentrate in a ball mill. the grinding kinetics, surface morphology, lattice distortion, wettability and moisture capacity were analysed. grinding kinetics equation was established based on population balances model with the size distribution data from a laser diffraction technique.
2017-8-4a magnetic separation process was investigated for the pre-concentration of low-grade vanadium-titanium magnetite ore. the results showed that 73.52 of feed ore were directly discarded for reducing the processing capacity of follow-up processing. a vanadium-titanium magnetite concentrate with 1.14 v2o5 22.22 tio2. read more
panzhihua steel plant adopts a new process - rotary hearth furnace (rhf) direct reduction - electric arc furnace (eaf) deep reduction - to manufacture iron, and the resultant ti-bearing slag contains 44.03% titanium dioxide and has higher contents of impurities such as calcium, magnesium and silicon, so it cannot be prepared titanium dioxide alone.
