Iron ore roasting temperature
WebAug 31, 2014 · The results show that the sequence of each factor affecting the acidolysis ratio of TiO 2 is: mass ratio of acid to ore, roasting time, and roasting temperature. The optimum technological conditions are obtained as mass ratio of acid to ore of 2.1, roasting temperature of 310 °C, roasting time of 75 min, and material particle size of 45–53 µm. The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. Magnetizing roasting uses temperatures between 700 and 900 °C for a time of under 1 hour to produce an iron concentrate (Fe 3 O 4) to be used for iron smelting.
