Abstract
A process for the beneficiation of an iron-containing material is carried out by first chlorinating the iron-containing material. Oxidation of ferrous chloride in the effluent gas from the chlorination is carried out under controlled conditions of oxygen supply so that more than 50% but less than 100% of the ferrous chloride is oxidized. In this way chlorine gas is separated from the process stream in a relatively pure form which can be utilized in a continuous process by recycle to another chlorination.
