LD Slag is produced during the separation of molten Steel Slag from impurities in steel-making furnaces. Slag being a complex solution of silicates and oxides is lighter and hence, floats on top of the molten mass of steel. It is then tapped into a Slag pot which solidifies on cooling and is then separated.
