With a view to satisfying the requirements of environmental protest and efficient usage of resources, a novel process for efficiently extracting vanadium v, titanium ti, and iron fe from vanadium-bearing titanomagnetite concentrate was developed.In the new process, vanadium is pre-extracted by additive-free roasting under the air atmosphere and alkaline leaching technologies.
Effects of calcium compounds on the carbothermic reduction of vanadium titanomagnetite concentrate vtc were investigated.It was found that calcium compounds had great effects on the metallization rate of the reduction product, the order of the metallization rate of reduction product being caco3 no additive caso4 cacl2, which indicated that the addition of caco3 was more conducive to.
Vanadium titanomagnetite concentrate was obtained.The total content of al 2 o 3, sio 2, mgo, and cao decreased to 7.The mass ratio of tio 2 sio 2 al 2 o 3 caomgotio 2 was 0.63, which makes the concentrate suitable for the production of titanium slag.Process mineralogy of the high-quality vanadium titanomagnetite concentrate.

Intermediate composition titanohematite, fe 2 y ti y o 3 with 0.7, is seldom the focus of paleomagnetic study and is commonly believed to be rare in nature.While largely overlooked in magnetostratigraphic studies, intermediate titanohematite has been identified as the dominant ferrimagnetic mineral in an array of late mesozoic and early cenozoic laramide clastic deposits.
The sintering pot test was used to investigate the effect of tio2 on the sintering behavior of chromium-bearing vanadiumtitanium magnetite cvtm sinter.The main characterization methods of x-ray fluorescence xrf, x-ray diffraction xrd, scanning electron microscopy-energy disperse spectroscopy sem-eds, and metallographic microscopy were employed.
The oxidation induration and reduction swelling behavior of chromium-bearing vanadium titanomagnetite pellets cvtp with cr 2 o 3 addition were studied, and the reduction swelling index rsi and compressive strength cs of the reduced cvtp with simulated coke oven gas cog injection were investigated.The results showed that the cs of the cvtp decreases and the porosity of the cvtp.

A process has been developed at the laboratory scale for leaching of vanadium from a vanadium residue using mixed hydrofluoric and sulfuric acid solutions, and naclo as an oxidant.The extraction studies were carried out using various acid concentrations, liquidsolid ratios, addition of oxidant, reaction temperatures and leaching times.The optimum leaching conditions were then determined.
Although the titanomagnetiteilmenite thermo-oxybarometer has been widely used to provide information on temperature and oxygen fugacity during magmatic and metamorphic processes, the available formulations yield unsatisfactory results for example, at high temperature and low to moderate fo 2 i.In conditions relevant to crystallization in basic and intermediate rocks.
Magnetic anomaly lows associated with the west hawk lake manitoba, deep bay saskatchewan and clearwater lakes quebec impact structures, are variable in lateral extent and intensity, a characteristic shared with most impact structures 1.Drill core from the centres of these structures provides a unique opportunity to ground truth the causes of the reduction in magnetic field intensity.
