摘要: Direct metal precipitation from loaded organic extractants by reaction with hydrogen may offer certain potential advantages over the conventional alternative steps of stripping and electrowinning in extractive metallurgy. As part an experimental programme involving interaction chelating hydrogen, thermal chemical behaviour Kelex 100 (an alkylated derivative 8-hydroxyquinoline) was studied. Copper found to precipitate stoichiometrically simultaneous regeneration l00/decanol/kerosene solvents hydrogen. The stability extractant some-what reduced when decanol removed system. In latter case, some limited hydrogenation quinoline nucleus impurities present observed. When heated under nitrogen, a slow dissociation observed resulting copper apparent regeneration.
