Ilmenite, also known as manaccanite, is a titaniumiron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steelgray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
The 40% grade is produced from slag and other vanadium products by the silicon reduction process. Vanadium additions to titanium alloys are made with aluminiumvanadium master alloys which are also produced by aluminothermic reduction of high purity vanadium oxides.

The kinetics of the decomposition of acid dissolved titanium slag with a sodium hydroxide system under atmospheric pressure was studied. The effect of reaction temperature, particle size and NaOHtoslag mass ratio on titanium extraction was investigated.
Preparing titanium dioxide from titaniarich slag (TiO 2 73wt%) by molten NaOH method has been developed. The effects of temperature and reaction time on the titanium conversion were investigated. The results showed that temperature had significant influence on the titanium conversion as well as the structure of the product.
The present invention belongs to the field of metallurgy, in particular to a method of separating titanium mixed titaniferous slag from a calciumcontaining vanadium. The method of the present invention is blast furnace slag flowing liquid melt mouth titaniumvanadium slag and converter slag containing mixed to form a mixed slag, blowing an oxidizing gas to the mixed melt, after blowing gas
There were two controlling factors, which should be kept balance of raw input and energy during titanium slag smelting in closed high power direct current electric arc furnace, DC furnace for short. The first factor contains compositions and ratio of input raw materials. Compositions of the raw could influence the progress and technical indiors of DC furnace smelting, and on the meanwhile

A Chinese Institute has expressed interest in technology transfer and investing in a titanium dioxide (pigment grade) manufacturing unit in Andhra Pradesh. The Institute of Process Engineering, a premier Chinese research institute has offered to give pollution free technology to convert titanium slag to pigment grade titanium dioxide to
This study aims to examine the mechanical properties and microstructures of steel/iron slag blended mortar (SISBM), which contains two byproducts of the steel and iron industries: steel slag (basic oxygen furnace slag, BOFS) and iron slag (blast furnace slag, BFS). Test results indie that steel slag will have effective hydration reactions with iron slag and contribute strength.

Abstract The water leaching process of vanadium, sodium, and silicon from molten vanadiumtitaniumbearing (VTibearing) slag obtained from lowgrade vanadiumbearing titanomagnetite was investigated systematically.
Nov 28, 2017 · But the Chinese government remains committed to chlorideroute production, with an effective ban on new sulfateroute capacity in the years ahead. And as a number of attendees pointed out to Industrial Minerals, this means that titanium slag production will have to increase.
The ease of slag removal for the principal flux types are: Rutile or acid fluxes large amounts of titanium oxide (rutile) with some silies. The oxygen level of the weld pool is high enough to give flat or slightly convex weld bead. The fluidity of the slag is determined by the calcium fluoride content.
An alternative route was proposed for preparing rutile titanium dioxide (TiO2) white pigment. The process involves the digestion of titanium slag with sulfuric acid, subsequent hydrolysis of unenriched titanyl sulfate solution with ammonia, lowtemperature calcination, and unseeded crystallization, producing a highquality rutile TiO2 white pigment.
The melting point and primary phase of titanium slag can be determined from the phase diagram with solidus projections. Therefore, in order to find the suitable composition of electric furnace titanium slag with high TiO2 content, the TiO2âˆ''CaOâˆ''SiO2âˆ''MgOâˆ'' Al2O3 phase diagrams were
