Abstract

21,884. Gill, J. Sept. 25. [Addition to 5618/09.] Iron oxides.-The process described in the parent Specification, which consists in producing ferric oxide by passing carbonic acid and air into a mixture of calcium carbonate and ferrous chloride liquors under pressure and at a temperature of about 180‹ F. is modified by working at a temperature of about 200-220‹ F., whereby magnetic iron oxide is precipitated. This is calcined to give ferric oxide of various shades.
