METHOD OF RECOVERY OF VALUABLE METALS FROM SUPERALLOYS (VERSIONS) Russian patent published in 2012 - IPC C22B7/00 C22B61/00 C22B1/02 C22B3/04 C22B23/00

Abstract RU 2447165 C2

FIELD: metallurgy.

SUBSTANCE: proposed method consists in valuable metals are decomposed in salt melt containing 60-95 wt % of NaOH and 5-40 wt % of Na₂SO₄. 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.

EFFECT: higher efficiency of extraction.
