Abstract
Rutile, which has been obtained by precipitation from a hydrogen chloride solution will contain a relatively large amount of residual chlorine containing compounds such as the various forms of titanium chloride. These residual chlorine containing compounds may be removed in an economical way by treating the rutile with hydrogen peroxide in an acidic solution at relatively low temperatures to substantially reduce the chloride content of the product.
