The invention discloses a treatment method for electrolytic copper waste liquid. The treatment method comprises the following steps of leaching, copper recycling, iron and aluminum removing and nickel recycling. According to the treatment method for electrolytic copper waste liquid, after copper is extracted and separated, chemical impurity removal and extraction impurity removal are combined, a high-purity nickel product is obtained, meanwhile, copper oxide ore and cobalt, zinc, manganese and other valuable metals in electrolytic copper waste liquid can be enriched to serve as by-products. 本发明公开了种电解铜废液的处理方法，包括以下步骤：浸出、回收铜、除铁铝、回收镍。本发明的电解铜废液的处理方法萃取分离铜后，采取化学除杂和萃取除杂相结合，不但得到了高纯镍产品，还将氧化铜矿和电解铜废液中的钴、锌、锰等有价金属富集起来，作为副产品。
