The commonly used magnetic mineral separators are SLON high gradient magnetic separator and medium magnetic drum separator. 3 Electrostatic separation Rutile is a good conductor of electricity, the resistance is only 102 – 10 Ω m, while the minerals such as silicate and zircon are non-conductors with a resistance of more than 1 000 Ω m.
Using these three techniques, only 23 percent to 42 percent of the TiO2 was recovered. The TiO2 content of the table tailings could not be made lower than 0.5 percent. Magnetic separation tests were conducted on as-received samples and on material ground to minus 200 mesh. The tests were carried out in wet, high-intensity magnetic separators.
The photocatalytic performance is connected to the large surface area of graphene derivatives (e.g. GO) that limit electron–hole recombination for TiO2, while the presence of magnetic …

Based on Langmuir-Hinshelwood kinetic model, apparent rate constants of Fe2O3-TiO2 and P25 were 9.2 × 10-3 and 2.7 × 10-3 min-1, respectively. The present study revealed not only the potential of using magnetic Fe2O3-TiO2 in PPME treatment but also demonstrated high reusability and easy separation of Fe2O3-TiO2 from the wastewater.
Photocatalysts, TiO 2 /C/RM, were prepared from TiO 2, tar pitch and red mud (RM).. RM and Fe 3 O 4 are in the bulk and on the surface of the carbonaceous matrix.. TiO 2 particles were agglomerated on the photocatalysts surface.. The photocatalysts showed high efficiency to discolor the remazol black dye. • The photocatalysts can be separated from the reaction by a magnetic field.
N-doped TiO 2 with oxygen vacancies exhibits many advantages for photocatalysis, such as enhanced visible light absorbency, inhibition of the photogenerated charge carrier recombination, etc. However, preparation of N-doped TiO 2 with oxygen vacancies under mild conditions is still a challenge.
