Abstract
A process for obtaining chlorine and iron oxide from iron chloride by adding iron oxide to iron chloride prepared by chlorinating iron-containing titanium ore, in an amount of above 10 percent by weight of the resulting mixture, charging the mixture in solid phase into a fluidizing roasting furnace for oxidizing roasting, extracting the overflow from the fluidized bed in the furnace, and charging the extract into another secondary furnace for additional oxidizing roasting. The iron oxide thus obtained is cooled and recycled to the fluidized bed in the primary fluidizing roasting furnace for the purpose of controlling the reaction temperature in the furnace.
