FIELD: metallurgy. SUBSTANCE: invention relates to the method and device of preparation slag-soda charge containing vanadium for oxidising roasting. The method involves crushing the slag, magnetic separation, breaking, mixing it with chemical additives for the follow-up roasting. Before roasting the resulting mixture is granulated, and the slag is crushed in several steps classifying …
FIELD: metallurgy; processing metallurgical slags. SUBSTANCE: proposed method consists in magnetic separation of each fraction of slag performed separately, thus obtaining conditioned metal, intermediate product, and pure slag. Magnetic separation of slag fraction more than 5 mm is carried out in magnetic field at intensity of 110-250 kA/m at linear velocity of material being …
