Abstract

PURPOSE: To recover alkali metal cpds. whose purity is enough for refining use by chemically treating an aq. soln. of slag obtd. by oxidative refining of molten iron alloy in the presence of alkali metal cpds. to remove cpds. of P, S, Si, etc. and insol. residue and then evaporating the soln.
