摘要： In the recovery of chlorine from iron chloride by causing reaction between an oxidizing gas and a gas containing iron chloride as the predominant constituent within an oxidation furnace, the initial meeting of the two reacting gases is caused to take place in an unobstructed space within the furnace, the oxygen being injected into the furnace in directions and at a velocity such that the resulting turbulent flow due to the initial collision of the two gases will not reach the furnace wall, whereby depositing of Fe.sub.2 O.sub.3 on the furnace wall is reduced to a minimum.

摘要： Artificial rutile of high TiO.sub.2 grade is produced by chlorine treatment of titaniferous ore such as ilmenite which comprises a combination of (1) a pretreatment step in which the ore is oxidized by roasting at a temperature below the sintering temperature thereof thereby to activate the ore, (2) a chloridization step in which the pretreated ore is subjected to a chlorine treatment in a fluidized bed chloridization furnace thereby to chloridize and remove selectively iron oxides within the ore without the formation of TiCl.sub.4, and (3) an aftertreatment step which comprises subjecting the ore to magnetic separation with a magnetic field of at least 20,000 gauses and further treatments thereafter, as necessary, such as a wet table treatment and electrostatic separation at from 5,000 to 30,000 volts.
