METHOD FOR CONCENTRATING AND SEPARATING amp;bgr;-2CaO·SiO2 FROM STEELMAKING SLAG

摘要

the present invention is a high value-added steel slag recycling it for -2CaO SiO ₂ relates to a method of concentrating and separating . More particularly, the present invention is -2CaO SiO ₂ efficiently concentrated and separated from the slag in order to be able to use as a cement admixture -2CaO SiO _{2 in slag} to a method for enrichment and separation. -2CaO SiO ₂ concentration and separation of the method according to an embodiment of the present invention, (a) drying and crushing of slag phase; (B) selecting a first non-complex of the steel-making slag by using a magnetic separator; (C) and the first non-powdered complex, the method comprising: selecting a material of low hardness by using a screen device; And (d) selecting a second non-complex of the material of the low hardness by using a magnetic separator; And (e) using an air classifier is characterized in that it comprises the step of selecting a material of a low specific gravity of the second non-complex. ;
