The Effects of Residence Time, Temperature and Particle size in Partially Reduction of Hematite to Magnetite VIA Fluidized bed Furnace, M.Sc. Thesis Sharif University of Technology ; Halai, Mohammad (Supervisor)
Abstract
The Effects of temperature, residence time and particle size has been investigated on partial reduction of hematite to magnetite VIA fluidized bed reactor. Since there is water crisis in Iran, it is not rational to use gravity separation processes. Rather the best way is to use magnetic separation. Ghazvin’s region non-coking coal was used for gasifying step in various temperatures in order to produce the gas reduction agent. Golgohr’s mine waste concentrate were tested as the initial iron ore. For the very first time, the residence time of the particles were investigated by the change of height of reaction chamber, in 3 different heights, and the highest i.e. 15 cm had the best results. As...
