ores for the main sources in the world are presented in Table 1 [1]. Extraction process. Generally, rutile and ilmenite ores are treated sepa-rately. The principal method in titanium ores treatment is to produce a concentrate of mineral via convention-al mineral beneficiation techniques [1, 15]. The ore is first crushed and ground.
