✦ Synopsis

Abstract

An acid process for the production of chromic anhydride from chromite ore has been developed on a pilot‐plant scale. The process, a modification of that proposed by Gresford and Wylie, was operated for six months to examine operating conditions and to determine data for design purposes. It was found to operate satisfactorily with both high‐ and low‐grade chromite ores and is suitable for large‐scale production of chromic anhydride.
