Natural ilmenite is the most abundant titanium bearing mineral in the earth's crust. The mineral ilmenite has been significantly grown since his discovery. Nowadays, it is the most crucial ore of titanium. The presented review shows the presence of enormous techniques for manufacturing titanium powder and titanium metal. Read More
2018 7 9 Leaching. The optimized conditions of leaching procedure were as follows: H 2 SO 4 concentration was 45% v/v, ore/acid ratio was fixed at 10% w/v g /mL, the reaction temperature was maintained at 130 C, the reaction time was 4 h, and the mixture was agitated at a speed of 600 rpm. Recovery of ilmenite leaching was obtained to be 85% for titanium and 90% for total
2022 7 9 Titanium slags produced through ilmenite electric furnace smelting contain 60–80%TiO2, a vital titanium resource in the titanium industry. The processing and utilization of titanium slag is faced with many challenges, such as complex mineral structures, high requirements, severe environmental pollution, and heavy additives and energy consumption.
Solutions of ilmenite FeTiO 3 and a titaniferous slag, in fused Li 2 O. 2B 2 O 3 and Li 2 O. 4B 2 O 3, yield on cooling compounds tentatively identified as LiFe 2. 5 Ti 3 O 9 and Li 2 Fe 3 Ti 2. 5 O 9 respectively. Both compounds are orthorhombic, and have the pseudobrookite structure. The ilmenite solutions yield, in addition, rutile TiO 2 .The yield of rutile increases from about 1 to
