Abstract
A manufacturing process for vanadium and chlorine-free sodium bichromate, which consists of concentrating a sodium chromate lye so as to cause the formation of neutral sodium chromate crystals tetrahydrate, separating the latter from their mother liquor, treating them with acid sulfuric and concentrate the solution obtained, after having separated the insoluble sodium sulfate formed, so as to cause crystallization of sodium bichromate.
