FIELD: processing of wastes. SUBSTANCE: method includes melting of multi-component material in graphite crucible. Temperature of process ranges from 1000 to 1800 C. Used as flux-forming slag is flux containing sodium fluoride in the amount ensuring viscosity of slag lesser than 4 MPa/s. After melting, melt is mixed and is kept in liquid state during period of time sufficient for separation of slag and metal phases. Then, slag and metal thus obtained are tapped and after solidification they are subjected to mechanical separation. EFFECT: low cost of process; enhanced efficiency. 4 cl, 1 ex
