PROCESS FOR REGENERATION OF CHLORINE FROM FERRIC CHLORIDE IN TITANIUM PRODUCTION

摘要

The invention relates to nonferrous metallurgy. A process for preparation of chlorine with its regeneration at treatment of titanium raw material is proposed. Ferric chloride is treated with sulphuric acid in presence of manganese dioxide with maintenance of ratio between reaction components of 1:(0.8-1.2):(0.9-1.2) under the temperature of 50-140 ºC with producing of chlorine, which is returned to the process, and secondary commercial end products - ferrous sulphate and manganese sulphate.
