Abstract
Raw materials (other than sand and similar materials containing a preponderance of free silica) for use in the ceramic industries are freed from iron by treatment first with reducing gases, and then with chlorine at red heat to volatilize the iron as chloride. The treatments may be repeated if necessary. Specification 325,386, [Class 1 (ii), Inorganic compounds, other than &c.], is referred to.
