<p>Titanium has wide applications. Titanomagnetite contains 1–20 wt.% TiO₂, accounting for about 23% of titanium’s total reserves. Titanium recovery from titanomagnetite is of great resource and economic value. Industrial titanium recovery from titanomagnetite concentrates is uneconomical at present. In the blast furnace process and the melting separation process, titanium enters the slag phase during smelting, where titanium is distributed in several mineral phases and is of low content, making it difficult to recover. In the roasting–leaching process, sodium and impurities accumulate in the residue, making titanium extraction from the residue difficult and uneconomical. Several potential methods for extracting titanium from commercial smelting titanium slags have been proposed, like the carbonization–chlorination and selective enrichment methods. However, these methods generally have disadvantages like environmental threats, high additive consumption, and high cost, hindering their large-scale industrialization. Titanium recovery from the leaching residue also faces commercialization problems. The difficulties in titanium recovery from Ti-enriched materials are mainly attributed to impurities. Future research should focus on the removal of impurities during metallurgical processes.</p>
