Get Free Sample Request @ https://www.marketresearchfuture.com/sample_request/5755 Titanium ore is a mineral containing titanium metal in the form of compounds and concentrations. Rutile has traditionally been the primary input in the manufacture of Titanium metal. Its name comes from the Latin rutilus meaning red. Its deep red colour is caused by iron impurities in its lattice. Rutile is formed under high pressures and temperatures as an accessory mineral in metamorphic rocks like eclogite. It is not economical to mine rutile from primary rock so it is recovered from weathered deposits in mineral sands.
