Abstract

152,399. Ballantine, W. B. July 9, 1919. Thermo-aluminic and like mixtures and metalextracting processes. - A process for obtaining chromium from chromic oxide or a mineral such as chromite, for the production of chrome-iron or chrome-steel alloys comprises the thermoreduction of the oxide of chromium with calcium carbide in the presence of an alkaline earth oxide, with or without the presence also in the mixture of one or more other reducing-agents such as. calcium silicide or aluminium. The alkalineearth oxide is preferably present in proportion at least equal molecularly to that of the calcium carbide. The reaction may be carried out within molten steel and the mixture may be enclosed in thin sheet iron cases to be immersed in themolten steel.
