Evaluation of Titania-Rich Slag Produced from Titaniferous Magnetite
Fluxless smelting of ilmenite to produce furnace slag as feedstock for the pigment industry is a well-established industrial practice with extensive installed smelting capacity globally.1,2,3,4 Commercial ilmenite smelters produce two products, namely titania-rich slag and a pig iron by-product. In contrast, smelting practices for titaniferous The selectivity of separation by LRMS is higher than IMRS. However, the greatest weakness of this separator is its limited capacity. In the case of separation rutile from leucoxene and garnet from monazite, LRMS can be effectively utilized, and the optimum feed rate could be from 1.5 to 2 t/h . 2.3.5 Cross-Belt Magnetic SeparatorMagnetic Separation SpringerLink

3.2 Magnetic core-shell structures. Taking into account the good magnetic properties of the magnetite-rich powder, this industrial product was used as core in the synthesis of Fe 3 O 4-TiO 2 and Fe 3 O 4-SiO 2 core-shell powders by using the reverse microemulsion method. Efficiency of the synthesis was determined as 76.3% for Fe 3 O 4-TiO 2 and 86.2 for Fe At 10 ppm of magnetite, blockage of the magnetic filters occurred. In the former magnetic filter design, the starting separation rate was 89% which remained quasi-constant for the first 10 minutes, but then decreased to 64% over the next 10 minutes (Shibatani et al. 2016).

Metalizing reduction and magnetic separation of
tion and magnetic separation is effective in achieving an efficient separation of iron from other elements in VTM [15]; however, this method is not feasible on an industrial scale because of low ore-treating capacity and the diffi-culty involved in selecting appropriate reactor equipment. Given the high strength and fast reduction Target separation of titanium magnetite and ilmenite can be realized for the HPGR product by parallel separation of Fe–Ti. Moreover, the new generation of micro–fine ilmenite can also be reduced. Finally, the TiO 2 recovery of ilmenite increases by 1.68% points higher than that from the JC product by the stage separation.Influence of different comminution flowsheets on the separation

A literature review of titanium metallurgical processes
The processes for production of pigment grade TiO 2 and titanium metal are schematically presented in Fig. 1. There are two processes to manufacture titanium pigment: the sulphate process and the chloride process. The two processes differ in both their chemistry and raw material requirements ( Hamor 1986).The characteristic temperatures of magnetite continuous crystallization with different TiO 2 concentrations magnetite were shown in Fig. 4, where the starting temperature of continuous crystals increased from 1088 K to 1185 K and the maximum shrinkage temperature increased from 1176 K to 1269 K as the TiO 2 content increased Particle migration behavior between TiO ScienceDirect
