The invention discloses an efficient copper extraction chemical used in cobalt wet processing, and relates to the technical field of nonferrous metal wet metallurgy. The efficient copper extraction chemical specifically comprises 40%-70% of ketoxime C9H19-C6H3(OH)-C(C2H5)=N-O, 1.0%-5% of ester C9H19-C6H4O-C(=O)-C2H5, 0.5%-1.0% of trisubstituted phenol (R1)2-C6H2(R2)-OH, 1.0%-2% of alkylphenol C9H19-C6H4-OH and 10%-39% of high boiling point solvent oil, wherein R1 and R2 represent alkane. By adoption of the technical scheme, the efficient copper extraction chemical used in cobalt wet processinghas the beneficial effects that the copper extraction capacity and extraction speed are high, the copper extraction recovery rate is also high, reverse extraction can happen easily and the quantity of three phases is small; and meanwhile, the extraction property is improved, production cost is reduced and the efficient copper extraction chemical is suitable for conducting copper extraction on substances like a cobalt-con
