Slag . The interaction of four types of commonly used refractories (, burned magnesite brick, magnesia carbon brick, corundum castable, and SiC castable) with slag formed in the smelting of titanium (wt. [TiO 2] = 80%) in an electric furnace at the Panzhihuan Iron and Steel plant was studied.
Aug 03, 2017· Also, the mineral phase of the meltingseparated titanium slag is stable, and has a compact structure. There is no mature process to deal with meltingseparated titanium slag at present. Only a small amount of meltingseparated titanium slag is used as a raw material to produce titanium dioxide pigment in sulfate process.
requires a pretreatment of titanium slag by fine grinding. It was found that grinding of titanium slag particles to 40 µm contributes to more complete decomposition of the anosovite with a formation of sodium titanates. It was found that during the sintering of titanium slag with soda at a mass ratio of slag:soda = 1:, decomposition of the ...

In the present study, the titanium slag, used as the raw material to prepare titanium dioxide, is manufactured by smelting ilmenite in an electric arc furnace, with anthracite as reductants (Pistorius, 2002).In this process, the titanium slag was first decomposed in NaOH system at lower temperature.
Titaniumrich slag A novel process for the extraction of iron, titanium, vanadium, and chromium from highchromium vanadiumbearing titanomagnetite concentrates is proposed. This process involves several steps: partial reduction of the concentrates, magnetic separation, hydrochloric acid leaching of the titaniumbearing tailing, and alkaline
ilmenite slag plants in china allstartheatrecoza Titanium Slag – Tronox Overview Ilmenite is reduced in an electric arc furnace to produce high titania slag and iron The titania slag is cooled crushed screened and sized in a slag processing plant to produce chloride grade slag . Email:query
Titanium slag: market prices of acid dissolved titanium slag and high titanium slag dropped further in Feb. and many manufacturers stopped production during Chinese Lunar New Year and refused to ...
The influencing mechanism of oxygen volume percent (%VO 2) on the acid solubility of the titanium slag during the oxidization at 1273 K (1000 °C) are investigated.%VO 2 has marginal effect on the phase composition evolution, but greatly affects the microstructure evolutions during the oxidation, that is, increasing %VO 2 promotes Fe outward migration and further results in the formation of ...
Jul 25, 2018· First, let''s take a look at the Titanium related products involved in the list, a total of 11 items. artificial rutile. Titanium ore and titanium concentrate, in addition to synthetic rutile. Titanium slag, titanium slag products containing more than 40% titanium. titanium dioxide

The market trend of various products is also quite different. Among them, the titanium dioxide market is a little weak with the price lowered slightly. However, the price of titanium slag finally increased after the price of titanium tetrachloride and titanium sponge continued to increase. While the domestic titanium concentrate price is much ...
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.

Commercial tests for fluidizedbed chlorination without sieve plate were carried out using titanium slag high or low in calcium and magnesium as main raw view of the fact that high calcium and magnesium content tends to cause agglomeration of the burden and blockage of the sieve plate which affects the normal process of chlorination,measures including gradual increase of blending ...
Jul 12, 2018· According to Neometals, the Chinese institute used for the test work has extensive experience in the processing and smelting of vanadiferous titanomagnetite ore systems, ... Neometals said that the results of smelting and slag cleaning produced a titanium slag that was potentially suitable as feedstock for titanium dioxide production.
Titanium dioxide (TiO2) has been widely used as pigment in paints, fillers for plastic and paper, coatings, adsorbents, cosmetics, catalysts, and gas sensors. A novel process for TiO2 production has been developed by the Institute of Process Engineering. This work develops the novel process by using the NaOH/KOH binary molten salt (50 mol % NaOH, 50 mol % KOH) instead of NaOH molten salt.
Owing to smelting vanadiumtitanium magnetite ore, the amount of iron entrainment in slag as droplets is far higher than that in conventional BF slag. However, the iron droplets can be easily settled by blowing air into the molten slag.
To recover pigment grade TiO2, operating plants all over the world use chemical processes. Slagbased technology is considered to be attractive because of low waste generation and low chemical cost due to high titanium content and is poised to replace the conventional technology. This paper provides a review of the slagbased technology with the specific aim to produce leachable slag and ...
