摘要： A process for recovery of copper from an aqueous ammoniacal solution containing copper values comprising: (A) contacting a copper pregnant aqueous ammoniacal solution containing copper values with a water insoluble beta-diketone copper extractant dissolved in a water-immiscible organic solvent to extract copper values from said aqueous ammoniacal solution into said organic solution thereby forming a copper pregnant organic phase and a copper depleted aqueous phase; (B) separating said aqueous phase and said organic phase; (C) contacting the copper pregnant organic phase with an aqueous acidic stripping solution; (D) separating said aqueous acidic stripping solution now containing the copper values from the organic phase; and (E) recovering the copper from said aqueous acidic stripping solution; characterized in that the beta-diketone extractant being a highly sterically hindered beta-diketone selected from beta-diketones of formula II: where R is phenyl or alkyl substituted phenyl, R' is alkyl having from above 1 to 8 carbon atoms, and R", R"' and R"" are the same or different and are chosen from the group consisting of H, alkyl having from 1 to 8 carbon atoms, and aralkyl having from 7 to 14 carbon atoms, with the proviso that (a) less than two of R", R"' and R"" are H and (b) the total number of carbons in all R groups is at least 13.

摘要： A process for recovery of copper from an aqueous ammoniacal solution containing copper values comprising:

(A) contacting a copper pregnant aqueous ammoniacal solution containing copper values with a water insoluble beta-diketone copper extractant dissolved in a water-immiscible organic solvent to extract copper values from said aqueous ammoniacal solution into said organic solution thereby forming a copper pregnant organic phase and a copper depleted aqueous phase;
(B) separating said aqueous phase and said organic phase;
(C) contacting the copper pregnant organic phase with an aqueous acidic stripping solution;
(D) separating said aqueous acidic stripping solution now containing the copper values from the organic phase; and
(E) recovering the copper from said aqueous acidic stripping solution; characterized in that the beta-diketone extractant being a highly sterically hindered beta-diketone selected from beta-diketones of formula II:
where R is phenyl or alkyl substituted phenyl, R' is alkyl having from above 1 to 8 carbon atoms, and R", R"' and R"" are the same or different and are chosen from the group consisting of H, alkyl having from 1 to 8 carbon atoms, and aralkyl having from 7 to 14 carbon atoms, with the proviso that (a) less than two of R", R"' and R"" are H and (b) the total number of carbons in all R groups is at least 13.

摘要： An improvement is disclosed in the solvent extraction process for recovering metal values, i.e. copper, from aqueous solutions, particularly aqueous solutions, containing copper and iron which may also include chloride, and more particularly to an improvement which provides for increased copper to iron ratios in the loaded organic extractant phase. The improvement comprises washing the loaded organic extractant phase prior to stripping of the copper values therefrom with an aqueous acidic scrub solution containing at least a portion of electrolyte.
