Ilmenite, as mined, has a high Cr 2 O 3 content which makes is unsuitable for direct smelting to titania slag. Some of this Cr 2 O 3 is removed at the mine when the ilmenite is passed through a magnetic separation step in which the highly susceptible Cr 2 O 3-rich fraction of the ilmenite is removed.

A process is provided for the production of titania rich slag from ilmenite. The ilmenite is fed together with carbonaceous reductant, and in the absence of fluxes, to the molten bath of a D.C. arc furnace. The molten bath of the furnace forms the anode and one or more electrodes in the roof of the furnace forms the cathode. A frozen lining is established and maintained between the refractory ...
titania slag with 94.5 mass percent TiO 2. The chemistry and mineralogy of these synthetic titania-rich feedstock's is unique among other industrial products and relatively complex due to several factors. 1) the high titania content of the metallurgical slag produced leads to the formation of syn-
high-titania slag, many studies(5)(6) were carried out on its investigation, but the present investigation is believed to be the first using fluidized beds. A difficulty in fluidized bed chlorination is the sticking and agglomeration of solid particles due to the formation of non-volatile chlorides. ...

Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray 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, inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Jul 18, 2013· AbstractWater granulation of high titania slag causes oxidation of some of the trivalent titanium in the slag to the tetravalent form; in smaller granules, some iron is also oxidized to ferric. Oxidation changes the phase constitution of the slag, with more rutile present (containing some iron oxide in solution). The chlorination rate (in a mixture of nitrogen, chlorine and carbon monoxide at ...
Ltd.-,-has been producing a high-titania slag from ilmenites by electric furnace smelting (12). Several years ago, the Bureau began in vestigating the use of lower grade do mestic titaniferous materials to produce titanium-rich slags for use as substi tutes for imported rutile in TiC14 pro duction.
3 THE DECREPITATION OF HIGH TITANIA SLAGS 3.1 BACKGROUND High titania slag is produced during the smelting of ilmenite in a furnace with a suitable carbonaceous reductant. In this process a large fraction of the iron content of the ilmenite is reduced to metallic iron. The remainder of the material collects in a high titania slag. The iron
Electro Smelting of Ilmenite for Production of Tio 2 Slag – Potential of India as a Global Player 825 The world's production of ilmenite was 10.85 million tonnes in the year 2005(2). The country-wise world production of ilmenite in the year 2005 is shown in Fi g. 2. While Canada (2.48 million tonnes) and .
Apr 22, 2016· UK: Rio Tinto's production of titanium dioxide slag has fallen by 24% year-on-year to 246,000t/year in the first quarter of 2016. The company said that its Iron and Titanium division had optimised production in line with demand. It reported that two of nine furnaces at Fer et Titane, Canada and one of four furnaces at Richards Bay Minerals, South Africa are currently idled due to low demand ...
Titania-rich slags with 80 mass percent TiO2 are produced in the electric arc furnaces of QIT-Fer & Titane, Inc., by the continuous smelting of hemo-ilmenite ore with anthracite coal. Titania slag represents an important feedstock for the manufacture of titanium dioxide pigment by the sulphate process. Moreover, part of the production of the titania-rich slag is further acid-leached under a ...

Thus, Ti slag prepared from the Panxi ilmenite contains high CaO and MgO, exceeding 5 pct of the slag content. This high CaO and MgO content confers considerable difficulty in producing titania (TiO 2) white using fluidizing chlorination. In this study, a new process named vacuum separation was found to produce high-grade TiO 2 materials.
high titania slag. For the purpose of this study decrepitation was defined as the disintegration or crumbling of a material into component parts or smaller fragments. This decrepitation process was simulated on a laboratory scale by heating various slag samples in air at .
The high conductivity of the slag causes the large potential drop and violent fluctuation of electric current (Pistorius and Coetzee, 2003, Sahoo et al., 1999). Addition of ESCM slag to the high titania slag leads to stabilize the electrical conditions and reduces the violent fluctuation of electric current.
The decrepitation of high titania slags was studied to gain an understanding of the mechanism of decrepitation. High titania slags consist mainly of a M 3 O 5 phase with an orthorhombic structure. The decrepitation was studied by oxidising high titania slag samples produced in a pilot plant furnace at temperatures between 400°C and 800°C.
