A process for copper recovery includes mixing a sludge cake with an acidic copper-containing rinsing waste liquid to form slurry; reacting the slurry with acidic SPS-containing effluent, nitric acid, sulfuric acid and liquid alkali to form a copper-containing reaction product; press filtering the obtained-above copper-containing reaction product to obtain a copper oxide-containing solid and a filtrate.
