The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce iron III oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres …

In the chloride-ilmenite process, ilmenite, which, even at high grade, has a substantially lower TiO 2 content (approximately 65%) than rutile, is converted to TiCl 4. 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

Possibilities For All Flotation Treatment of Titanium Ore. To develop a flowsheet for separation of high grade titanium-rutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is weakly magnetic.

titanium from its ore because the titanium reacts further with carbon, so a more reactive metal, e.g. sodium or magnesium, is used to reduce the titanium ore instead. £ For both titanium and aluminium: Extraction of these metals from their ores is expensive.
The iron is precipitated as hydrated iron oxide from the synthetic rutile grains and a mild acid treatment is used to dissolve the impurities and any residual iron. The grains of synthetic rutile are washed, dried and transported to titanium dioxide pigment manufacturing plants either in Australia or overseas for further processing.

The effectiveness of TiCl 4 as a chlorinating agent for the carbo-selective-chlorination of iron oxide was verified in this study. Thus, it was demonstrated that the carbo-selective-chlorination is feasible for the selective removal of iron directly from low-grade titanium ore containing 51% TiO 2 to produce high-grade TiO 2 feed in a single step.

Rutile is easy to process to titanium metal or TiO2 pigment by the chlorination method while ilmenite is more complicated because of its high iron content. Since the world reserves of titanium are 90% in the form of ilmenite and only 10% in the form of rutile, the treatment of ilmenite is evidently an important question in metallurgy [1,2].

Titanium is manufactured using what is known as the Kroll process. It involves the extraction, purification, sponge purification, alloy creation, and forming and shaping, which is only a brief overview of the entire process. At the beginning of the manufacturing process, the manufacturer receives the concentrates from the mines.
