ABSTRACT:
A process for separating different products from steelmaking slag includes reducing the average particle size of slag from a steelmaking process into fine particle size material, and separating the fine particle size material into at least an iron rich product and a silicate rich product based on the differences between these products in at least one or more properties including magnetic susceptibility, particle size or specific gravity.
