Abstract
A process for the chlorination of a material containing iron and titanium chemically combined with oxygen, comprising feeding the material to be chlorinated, in particulate solid form, into a reaction bed of solids containing ferrous chloride, and reacting it within that bed, at a temperature below the melting point of ferrous chloride, with a controlled amount of chlorine in the presence of sulphur in free or combined form, to produce solid ferrous chloride, titanium chloride, which is volatile at a temperature of operation, and sulphur dioxide, as the principal products of the process.
