摘要： Tungsten is recovered from alkaline brines by: (1) initial loading of metal values on an 8-hydroxyquinoline-resorcinol-formaldehyde resin, (2) selective desorption of boron, arsenic and sulfur from the resin by means of an NH.sub.4 Cl--NH.sub.4 OH solution having a pH of about 7.5 to 9.5, and (3) desorption of tungsten from the resin by means of water or an alkaline solution.

摘要： Valuable metals are recovered from superalloy scrap by a series of process steps comprising (1) dissolution of the scrap in chlorinated acidic aqueous solution, (2) removal of tungsten and silica by adsorption on activated carbon, (3) extraction of molybdenum with a water-immiscible organic phosphate or phosphonate, (4) extraction of iron with a water-immiscible secondary amine, (5) extraction of cobalt with a water-immiscible tertiary amine, (6) precipitation of chromium as a hydrous basic sulfate, and nickel recovery.
