The ore burden preparation plays a very vital role in the improvement of the blast furnace productivity. Ore processing has been employed to the ore burden prepa-ration by way of sizing the ore and beneficiation.Titanium and iron are closely related in nature, although titanium is the ninth most abundant element in the Earths crust. Iron in titanium ores must be removed for use as feedstocks in the manufacture of titanium dioxide pigments and pure TiCl4 for metal titanium. In this study, various beneficiation processes of ilmenite for production of TiO2 have been reviewed and compared.Apr 03, 2014 Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 70 iron, hematite or Fe3O4 72 iron. magnetite. Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total .

METHOD A sample of ground graphite was weighed up to 300g using the triple beam balance. Distilled water of up to 1000cm3 was measured and mixed with the graphite ore, poured into the flotation cell and agitated for 2 minutes at the speed of 1500rpm.rutile ore, this work is therefore expected to provide useful data on the kinetic parameters on the leaching of the ore for its subsequent beneficiation.

    These two ore samples were however found to have a high TiO2 content of 20.36 and 33.38 respectively. Although the Otu figure is lower than that of a recently studied rutile sample 24, it would be appropriate to treat the ore primarily for rutile recovery andThese two ore samples were however found to have a high TiO2 content of 20.36 and 33.38 respectively.The ilmenite ore used in the process contains a much larger amount of iron than the other ores i.e., rutile or high-grade ilmenite used to produce TiCl 4.Beneficiation of bauxite containing less than 4-5 silica was not found to be justifiable especially in view of the depletion of ore reserves.
