METHOD OF SEPARATING MULTICOMPONENT MATERIAL CONTAINING METALLIC COMPONENTS Russian patent published in 2005 - IPC

Abstract RU 2248406 C1

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.
