This paper reviews a study on processing titanomagnetites using low-temperature treatment and magnetic separation. Using a reduction agent (15 %), chloride additives (15 %), and calcium fluoride (5 %) in low-temperature treatment reduced titanium magnetite iron content. This process extracted iron from titanium precisely and thoroughly. The best low-temperature treatment time and temperature were 60 minutes and 1200 °C. Magnetic separation with 0.2 T magnetic field intensity yielded 75.5 % magnetic fraction. Titanomagnetites treated at low temperatures had 50.9 % magnetic portion iron. Magnetic fraction iron extraction was 97.8 %. The yield of 24.5 % was achieved while the non-magnetic concentrates titanium dioxide content grew to 65 %.
