Status of titanium slag production technology abroad

The Tinf0s production plant of the shares, this is a strong feed. Table 8 is also a pre-climb and finished titanium slag and chemical composition of raw materials (%) Table8Chemicalcompsitionofprereducedrawmaterialandfinishedtitaniumslag and for funding the transformation of the plant. By Tyssedal plant, BHP in the cheap electricity can Make slag titanium minerals production costs low. 4 Conclusion ilmenite smelting slag with not only enriched TiO:, and the recoverable ilmenite iron, so that comprehensive recycling. Slag titanium dioxide for sulfuric acid production savings, reduce emissions of ferrous sulfate and waste acid will help protect the environment. Chloride, titanium dioxide and titanium slag for production of titanium sponge,[link widoczny dla zalogowanych], compared with the direct use of ilmenite can reduce chlorine consumption. Therefore, foreign and sponge titanium dioxide slag commonly used industrial materials such as titanium-rich material, titanium slag production capacity abroad in 2005 reached 3x106t / a. Different grade of slag, and its different uses. Low-grade titanium slag (TiO270% 80%, FeO8% 12%) calcium and magnesium content is generally high, with good acid, titanium dioxide is mainly used for production of sulfuric acid; high-grade titanium slag (TiO285% ~ 95%, FeO3% ~ 4 %), calcium, magnesium content is low, mainly for the production of chloride oxidation roasting TiC1 and synthetic rutile production. Titanium slag electric furnace smelting process,[link widoczny dla zalogowanych], closed under way electric smelting furnace can be divided into closed and semi closed electric smelting furnace smelting and exposure. Closed electric furnace smelting is the world's most advanced production methods. High level of titanium slag production technology abroad, the production conditions are good. Electric equipment to achieve a larger and fully enclosed high degree of automation. The world with high levels of titanium slag smelting technology, mostly in Canada, South Africa, Norway and Ukraine. Quebec Iron Titanium Corporation (QIT), South Africa,[link widoczny dla zalogowanych], Richards Bay Iron Titanium Corporation (RBM) and the Norwegian company Tinfos ilmenite smelting furnace slag with a large enclosed, to achieve continuous feeding smelting, pollution, high degree of automation.
