Method for extraction of metals from slag melt includes melting output materials in furnace, formation of filtering layer of metal melt, extraction of metal components from initial melt in process of passing it through layer of molten metal with formation of layer of demetalized slag melt over metal melt and separate discharge of metal and slag. Filtering layer of metal melt is formed in the lower zone of furnace for melting initial materials. Output melt through filtering layer of metal is passed twice, at that first from up to down, and then- from down to up due to hydrostatic pressure of column of initial melt in combination with discharge of slag over metal layer through branch pipe of siphon device. At that ratio of product of height of initial melt and specific density of slag and product of height of layer of metal melt and specific density of metal is kept at level 1,1÷1,5. |
