effect of titanium in iron ore

Sintering Characteristics of Titanium Containing Iron Ores

Titanium-bearing iron ores are found in many large deposits around the world and are becoming an important alternative source of iron ore due to the shortage of economic high purity ores. For instance, high titanium (and vanadium) magnetite concentrates account for more than 14% of China’s national iron ore resources.

Sintering Characteristics of Titanium Containing Iron Ores

The effect of Ti-oxide on the sintering behaviour of iron ore has been studied by doping pure TiO 2 to a sinter blend in laboratory tests. The results showed a considerable effect of TiO 2 on sinter strength, where the tumble index increased with increasing TiO 2 % (up to 2.0%). However, doping more than 2.0% TiO 2 to the sinter blend decreased its strength.

The Effect of Titanium on Reduction Degradation of Iron

The effect of titanium oxide in solid solution in magnetite on the magnetite to haematite transformation rate was studied first in order to simulate the final stage of the sintering process. In other experiments, haematite samples doped with 0.5, 2.0 and 5.0 wt per cent titanium oxide were studied using thermogravimetry under a controlled gas

Efficient separation of vanadium, titanium, and iron from

Jan 15, 2021· 1. Introduction. The vanadium–bearing titanomagnetite (VBT) is a strategic and complex iron ore, which containing valuable metals of vanadium, titanium, and iron used as constituents of several alloys, whitepigments, and steel,, .In China, the gross reserve of titanium in VBT ore is estimated to be about 1.18 million tons, accounting for 93% of China’s total domestic reserve of titanium

Experimental Study of the Effect of B2O3 on Vanadium

The iron ore used in this study is vanadium-titanium concentrates obtained from southwest of China. This was used together with bentonite and B 2 O 3 (≥98%). The chemical composition of the sintering raw materials is shown in Tables 1 and 2. The B 2 O 3 was added in increments of 0.20% yielding 11 experiments with B 2 O 3 ratio in the range 0

Effects of Iron Sand Ratios on the Basic Characteristics

Jun 22, 2016· Effects of iron sand ratios on the basic characteristics of vanadium titanium mixed ores were investigated using micro-sinter and grey relational analysis methods. The results show that iron sand presents poor assimilability, poor liquid flow capability, and low bonding phase strength. As the iron sand ratio in vanadium titanium mixed ores increases, the mixed ore’s assimilation temperature

ILMENITE (Iron Titanium Oxide)

Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3.

Effect of B2O3 Content on the Sintering Basic

The sintering basic characteristics of iron ore play a key role in the process of sintering. In this study, the effects of B 2 O 3 on the assimilation characteristics, softening temperature, fluidity of liquid phase, compressive strength of bonding phase, and microstructure of the mixed fine powder of hematite and vanadium-titanium magnetite (H-VTM) are studied.

A kinetic study of the leaching of a Nigerian ilmenite ore

Jul 01, 1999· The effect of agitation on the dissolution of titanium and iron was investigated in 7.2 M HCl solution with the 53–74 μm size fraction of the ilmenite at 70°C, using stirring speeds of 100–500 min −1.The results in Fig. 1 show that the dissolution rates are independent of the stirring speed. The diffusion in the liquid film is not the rate-determining step of the dissolution reaction

Iron ore Wikipedia

Iron ore being unloaded at docks in Toledo, Ohio. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe
