The overall process. Titanium is extracted from its ore, rutile - TiO 2. It is first converted into titanium (IV) chloride, which is then reduced to titanium using either magnesium or sodium. Conversion of TiO2 into TiCl4. The ore rutile (impure titanium (IV) oxide) is heated with chlorine and coke at a temperature of about 1000°C.

3. Related tin extraction equipments. Tin exists almost in the form of cassiterite (tin oxide) in the earth's crust. Its density is relatively large, so gravity separation is most used for tin extraction. In the pre-dressing stage of tin oxide ore, the common equipments are trammel screen, cyclones, rod mills and other equipment.
