METHOD FOR LITHIUM RECOVERY FROM WASTES OF ALUMINUM-LITHIUM ALLOYS Russian patent published in 1994 - IPC

Abstract RU 2016140 C1

FIELD: nonferrous metallurgy; metal wastes utilization. SUBSTANCE: metal wastes of aluminum-lithium alloys are subjected to electrochemical contact with metal extractant in a salt bath. Then lithium is extracted from is resultant alloy with the metal extractant by means of a three-layers electrolytic refining in a salt bath at a lower temperature than by direct refining of the aluminum-lithium alloy. EFFECT: metallic lithium recovery. 1 dwg, 1 tbl
