FIELD: metallurgy. n SUBSTANCE: proposed method consists in valuable metals are decomposed in salt melt containing 60-95 wt % of NaOH and 5-40 wt % of Na 2 SO 4 . Then, melt decomposition product is converted into solid phase by cooling to room temperature. After cooling, minced melt decomposition product is converted in water at temperature lower than 80°C to produce water suspension and water fraction is separated by filtration for components to be extracted therefrom. n EFFECT: higher efficiency of extraction. n 22 cl, 1 dwg, 3 tbl |
