Abstract

1412486 Treating slags; cements GRANGES AB 15 Feb 1973 [15 Feb 1972 (2)] 7525/73 Heading C1H and C1K [Also in Division C7] A metallurgical slag is tapped and then treated with carbon and a material containing silicon or aluminium in free or combined form at such a temperature as to prevent foaming and allow metal originally in the slag and that produced by reduction to sediment out. The slag is treated with lime or an aluminium-oxide containing material to make it of suitable composition for addition to Portalnd white or aluminate cement, or as a cement itself.
