THE ESTIMATION OF SLAG PROPERTIES

Slags are very important to the production of clean metals. The old adage "Look after the slag and the metal will look after itself" is very appropriate. Slags have a wide range of composition: Metallurgical slags are usually based on the CaO-Al2O3- SiO2 system Non- ferrous slags are frequently based on fayalite- eg FeO.SiO2
