AbstractCrystallization behavior, liberation and beneficiation of Ti-rich phases precipitated from Ti-bearing slag of smelting process for titanomagnetite were systematically investigated. For the slags containing 40-55 % TiO2, anosovite can precipitate as the main Ti-rich phase, especially as the TiO2/MgO/Al2O3 content is relatively high and basicity [R = w(CaO)/w(SiO2)] is low. In particular, as the content of MgO is low, crystallization of rutile is dominant and most of the Ti element is enriched in rutile. Based on the results of variation in the Ti enriched phases within the whole composition, the crystallization diagram of Ti-rich phases has been constructed in the present study. Slags with compositions being in the optimal ranges in the crystallization diagram shows the most satisfactory liberation degree and beneficiation response. By gravity separation, the TiO2 content of the slag can be upgraded to nearly 70 %. In addition, compared with perovskite and rutile, anosovite grains show much bigger sizes since the growth of anosovite crystals is easier under the same condition.
