摘要

2. Section 1 of the application discloses a method for recovering metals from aqueous solutions containing metals at high temperature, which is characterized by:o Contacting a metal-containing aqueous solution with an organic phase comprising a water immiscible solvent and a reagent composition comprising a ketoxime having a structure represented by (R5) (R4) (R3) (R2) (OH ) C6H3C (R1) = NOH,R1 is a linear or branched tar or alquenilo c7-22 of c1-22, arilo C6 or aralquilo c7-22;R2-r4 refers to hydrogen, halogen, linear tar or C6-12 derivative, linear tar or c1-22 derivative containing R6, linear adhesive or c2-22 derivative, arilo C6 or aralquilo c7-22;R5 is a linear tar or c1-22 derivative; at least a part of metal can be introduced into the organic phase to provide a metal filled organic phase and a metal poor aqueous phase;o. The organic phase filled with metal is separated from the dissolved metal phase;Or recover metal from organic phase containing metal.
