METHOD OF SEPARATING MULTICOMPONENT MATERIAL CONTAINING METALLIC COMPONENTS

摘要

FIELD: waste treatment. ^ SUBSTANCE: multicomponent waste material is preliminarily impregnated with solution of salt of metal-collector in amount ensuring weight content of metal-collector in melt exceeding content of metallic components therein. Material is then calcined and melted in reductive atmosphere after addition of slag-forming flux based on metal fluorides. Melt is stirred and kept in liquid state over a period of time long enough to allow separation of slag and metallic phases. Resulting slag and metal are tapped and mechanically separated when solidified. ^ EFFECT: achieved high degree of recovering metals in collecting alloy at minimum expenses. ^ 8 cl
