摘　　要： Facts affect recovering copper from spent ammoniacal etchant by extraction using Lix 54-100 were analysised.Copper amount in spent etchant whose copper concentration reached 150g/l could decrease to the level of fresh etchant in one or two stage,when phase ratio(O/A)was 2/1,and 80% Lix 54-100 was used as organic phase.
