The Analysis of Silicate Slags

JSGT 1927 V11 T177-T189

 Since almost all metallic ores are, in nature, associated with either free silica or silicates, it follows that the slags formed in most metallurgical processes for the reduction of such ores are more or less siliceous in character. Further, in such metallurgical processes, the progress of the reactions, whereby the metal is purified, is estimated to a large extent by observations upon the character of the slag, these observations being directed towards the physical properties of fluidity, colour, etc., and supplemented by simple analytical tests.
