Abstract

PURPOSE: To recover alkaline metal from an aqueous solution of a slag formed during ferro alloy refining by the slag containing alkaline metal compound, and combustion is conducted in the aqueous solution to remove the contained S and the solution is reused as a raw material for refining slag.
