ABSTRACT:
The invention relates to a method for the reduction of ferric chloride to produce ferrous chloride. The method comprises using gaseous sulphur or a gaseous sulphur chloride in which the atomic ratio of sulphur to chlorine is more than 1:1 as the reducing agent. The reaction is conveniently performed in a fluidised bed. According to a particular aspect, the ferric chloride reduction forms part of a process for the recovery of chlorine values from iron chloride by-produced by industrial processes such as the chlorination of a titaniferrous or aluminous material.
