Removing recovery method and apparatus of copper from copper-containing acidic waste liquid

A strongly acidic waste liquid copper, such as waste of industrial waste copper chloride has been disposed of as containing waste etching solution and the electrolytic copper foil plating bath containing a high concentration is treated in an efficient and low sludge formation amount , to provide a method and apparatus for recovering copper oxide as a precipitate. A mixed solution of copper-containing acidic waste liquid and the oxidizing agent is poured into an alkaline solution, to obtain the resulting solids recovery method and the method of copper from copper-containing acidic waste liquid, wherein recovery system of copper from copper-containing acidic waste liquid to be used. .FIELD 1
