iron ilmenite processing
ILMENITE (Iron Titanium Oxide), Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3 The structure is composed of alternating layers of cations and oxygensHow to Separate Ilmenite?, Ilmenite is brittle and dense Due to the physical and chemical properties of mineral surface, it is not easy to recover coarse ilmenite by flotation process However, fine or fine ilmenite has good floatability and can be recovered by flotation method 1 Flotation Process 1) Conventional flotation method In the conventional flotation process ,(PDF) A New Process to Upgrade Ilmenite to Synthetic ,, Altair Process The Altair process (Verhulst, et al, 2002, 2003) is under development in USA is based on leaching of ilmenite concentrate containing 522 % TiO2 and 328 % Fe in hydrochloric acid to solubilise titanium and iron while silicates and chromites remain in the residueOptimization of Ilmenite Dissolution by Synergistic Effect ,, Many researches have reported the application of the hydrothermal process for ilmenite Direct leaching of ilmenite can be performed using inorganic acids or organic on Different scholars investigated the leaching of ilmenite by sulfuric and hydrochloric acids at different conditions of acid dosages, temperatures, acid to ore ratios ,Ilmenite smelting: the basics, The two main routes to upgrade ilmenite to chlorination feedstock are ilmenite smelting, and the synthetic rutile route Synthetic rutile is produced by solid-state reactions; for example, in the Becher process (as practised widely in Australia) ilmenite is reduced to a mixture of metallic iron and rutile; the iron is then removed by leaching.
