A method for removing dissolved alkali metals and alkaline earth metals from aluminum is disclosed. The method comprises providing a body of molten aluminum containing the alkali metal and alkaline earth metals in a container and inductively moving the molten aluminum in upper regions of the body in a generally downward direction at outward regions of the body and in a generally upward direction in inner regions of the body. Fluoride values are added to the body to react with the alkali metals or alkaline earth metals.

Aluminum scrap recovery by inductively moving molten metal

A process for decomposing chlorinated hydrocarbon compounds wherein the compounds are heated to an elevated temperature of about 800.degree. to 1200.degree. C. and reacted with alumina and a reactive carbon source. A preferred operating temperature is about 800.degree. to 900.degree. C. and preferred carbon sources are activated carbon and coked alumina. The process is particularly useful for disposing of chlorinated organic compounds that are generated in the production of metal chlorides by chlorination of a metal oxide in the presence of carbon.
