Title: Process for the production of chromium oxide from chrome iron ore
IPC: C01G37/02
Filed: 1922-09-22
Abstract: Chromeiron ore is converted into ferrochromium in the known manner, the ferrochromium is dissolved in hydrochloric acid, and the chromium precipitated as hydrated oxide by calcium or barium carbonate.  The precipitate is separated and used to produce alkali chromate or chromium salts.  The filtrate, if barium carbonate was used, is evaporated and cooled to separate barium chloride and the mother-liquor may be evaporated to obtain ferrous chloride.
