Abstract

Procedure for preparing a basic fluidizing product for steel slag, characterized in that 40 to 80 parts by weight of powdered alkali metal hydroxides and/or carbonates are dry mixed with 20 to 60 parts by weight of a substance known per se. favors fluidization, and because said powdery mixture is compressed into small molds to form pieces with dimensions not less than 4mm in diameter.
