·Leaching titaniferous magnetite concentrate with alkali solution of high concentration under high temperature and high pressure was utilized to improve the grade of iron in iron concentrate and the grade of TiO 2 in titanium tailings The titaniferous magnetite concentrate in use contained % TiO 2 and % Fe The thermodynamics of the
·Vanadium titanium magnetite gravity separation magnetic separation flotation Stage 4 Magnetite dehydration Since the iron concentrate after separation contains some water dehydration treatment is required 1 The separated iron concentrate slurry flows into the thickener for sedimentation to remove a large amount of water
·The purpose of this research was to determine the effect of CO addition to H2 on the reduction kinetics of magnetite concentrate particles at high temperatures Experiments were carried out at 1 673 K The replacement of N2 by CO enhanced the reduction rate considerably The kinetics of CO reduction is slower than that by hydrogen but significant and the
·A novel ironmaking technology is under development at the University of Utah The purpose of this research was to determine comprehensive kinetics of the flash reduction reaction of magnetite concentrate particles by hydrogen Experiments were carried out in the temperature range of 1423 K to 1673 K 1150 °C to 1400 °C with the other experimental
At the Iron Ore Company of Canada s Carol Project low intensity magnetic separation is used as an initial cobbing step on the cyclone overflow of the ball mill discharge to remove magnetite This magnetite concentrate is then combined with the tailings of spiral gravity concentrators to be fed to a rougher wet drum low intensity separator
·The specific gravity of magnetite concentrate was measured by a pycnometer method The chemical analysis of magnetite concentrate and bentonite was determined by XRF and wet chemistry methods The moisture content of green pellets was evaluated using an infrared moisture analyzer MA160 Sartorius China according to ISO 3087
·magnetite concentrate which contains vanadium Figure 4 The concentrate is pre reduced and then smelted to produce 700 000 tpa pig iron and steel The project has been operating for many years The 700 000 tpa of slag containing 35% TiO 2 is sold to Chinese
