crude titania-rich slag is further acid-leached under a high-pressure and moderate-temperature hydrometallurgical process to yield an upgraded titania slag with 945 mass percent TiO 2 The chemistry and mineralogy of these synthetic titania-rich feedstock’s is unique among other industrial products and relatively complex due to several factors
In ilmenite smelting, the iron content of the oxide is also lowered by reduction to metallic iron, but this takes place in the liquid state, at a much higher temperature (of around 1650°C) Ilmenite smelting thus yields two products: a titania-rich slag, and molten iron This is in contrast with the Becher process.
A method of preparing a pre-reduced ilmenite ore for smelting, wherein metal oxides contained in the ore are selectively reduced in solid-state reactions over titanium oxide, the method including the step of pre-reducing carbon-based pellets of the ore
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide
