Titanium is very rich in reserves on earth. There are more than 140 kinds of titanium-bearing minerals in the earth's crust, but there are only more than ten kinds of mining value. The mined titanium mineral deposits can be divided into two types: rock deposits and sand deposits. Rock deposits are igneous rock deposits, which have the characteristics of concentrated deposits and large reserves. The content of FeO (relative to Fe2O3) is high, the content of gangue is large, and the structure is dense. Most of them are commensal ores. The main minerals of this type of deposits are ilmenite and titanomagnetite. The ore beneficiation and separation are more difficult. The content of TiO2 produced in the titanium concentrate is generally not more than 50%.
The placerite deposit is a secondary deposit, which is formed by weathering and stripping the rock deposit and then enriched by water flow, mainly concentrated in the coast, river beach, paddy field and other places. The minerals include rutile, sand-like ilmenite, brookite, white titanium The characteristics of this mineral are: high Fe2O3 (relative to FeO) content, loose structure, and easy separation of impurities. Most of the selected concentrates contain more than 50% TiO2.
