liquid slag samples, the majority of the samples are from steel slags 14,15. In the case of ilmenite smelting, the slag analysis becomes very important as the slag composition changes rapidly with process condition and any delay in slag analysis can alter the slag composition in the furnace.
The principal mineral sources of titanium are rutile, anatase both TiO2, ilmenite FeTiO3 and leucoxene a weathered ilmenite of variable concentration of TiO2 but similar to pseudorutile Fe2Ti3O9. These titaniferous minerals along with their value added products like Synthetic Rutile and TiO2 slag constitute Titanium Feedstocks for TiO2 pigment, Ti metal and welding electrodes ...
Ilmenite smelting is a reduction process in which the FeO in ilmenite is reduced to Fe, giving a titanium-rich slag on top of pure pig iron .Slags analysis is of great importance in ilmenite smelting as the slag contains the titanium oxide and the pure pig iron is the by-product 2,3.The slag composition is checked during the process to see the titania content.

Pilot-Scale Demonstration of Ilmenite Processing Technology UMD NRRI ii Executive Summary The ...
by the sulfuric acid process 7. The slag was treated in the same way as ilmenite with the exception that no separation of ferrous sulfate was necessary because the bulk of iron was already separated by reduction in the earlier step Figure 13. The sulfuric acid treatment process of the slag, however, still suffered from the disposal problem ...
4.1. TiO2 Slag Ilmenite smelting is a carbothermic process to upgrade the mineral ilmenite, yielding TiO2-rich slag which is mainly used as a feed stock for TiO 2 pigment production as primary pr oduct and pig iron as a by-product. This smelting process is unusual in having slag as its primary product and metal as a by-product. Another
Titanium dioxide slag is the principal product, with pig iron being a co-product. Titanium dioxide slag is largely used as a raw material for producing white pigment, mostly for the paint and plastics industries. Richards Bay Minerals Process Flow. Basic reactions in ilmenite smelting are Reduction of FeO from slag. FeO C Fe CO
Titanium rich slag has emerged as a raw material for alternative titanium source. Ilmenite contains 4250 TiO2 as the mineralogical composition depending on the geographical resources. Application of titanium in paper, plastic, pigment and other various industries is increasing day by day. Due to the scarcity of natural raw mineral rutile TiO2, ilmenite is considered as precursor for the ...
process or rotary kiln nonslagging process to form metallic iron and titanium oxide 2. Several technologies today are using smelting technique to produce TiO2 slag and pig iron from ilmenite ore 3. In this process, most of the Fe2O3 and FeO are reduced to metallic iron with a small amount of ferrous iron left in the slag to make it ...
Therefore, pre-reduction of ilmenite concentrate is essential to minimize the energy consumption during thermal plasma process. Thermal plasma processing of ilmenite for the production of titania rich slag is considered to be the direct route to meet the current demand of industrial needs of titanium.

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 ...
Basic procedure of ilmenite smelting and rational Ti slag grade in pyrometallurgical process have been summarized and analyzed. The rational Ti slag grade is related to reduction degree, FeO content and assistant dissolve impurities, with important influence on smelting condition and acid decomposition.
