the 1920s after titanium dioxide was first used as a pigment in 1908 when the French metallurgist A.J. Rossi mixed titanium dioxide with salad oil and brushed out the mixture.11,12 It is technically feasi-ble to upgrade ilmenite directly via the sulphide or chloride process, but excessive waste streams would be generated.

The experiments were conducted under 15 % water content and 400 W microwave power conditions. Titanium slag samples with masses of 10 g, 20 g, 30 g, 40 g, and 50 g were subjected to microwave drying using the controlled variable method. The mass of each titanium slag sample was measured at 20-second intervals throughout …

Titania slag represents an important feedstock for the manufacture of titanium dioxide pigment by the sulphate process. Moreover, part of the pro-duction of the titania-rich slag is further acid-leached under a high-pressure and moderate-temperature hydrometallurgical process to yield an upgraded titania slag with 94.5 mass percent TiO 2, which

Vanadium titano-magnetite is an important iron ore resource containing iron, vanadium and titanium. Although iron and vanadium can be recovered by the traditional blast furnace process, titanium can only be stored in the form of TiO2 bearing slag, which resulting in a great waste of titanium resources.

In the Ti slag production process, the iron oxides are reduced to metallic iron, thereby producing a TiO2-rich slag and high purity iron. TiO2 is produced from either ilmenite, rutile or titanium slag. Radioactive elements associated with heavy mineral deposits may be removed from the ilmenite concentrate before smelting or, alternatively, from ...
