  • Method and apparatus for removing and recovering copper from copper-containing acidic waste liquid and method for producing copper-containing substance
    Patent number: 9243307
    Abstract: The present invention relates to a method and apparatus for removing and recovering copper by treating an acidic waste liquid containing copper ions such as an etching waste liquid resulting from etching a copper printed board in an etching solution of cupric chloride and a waste liquid after renewing a plating bath liquid in producing electrolytic copper foil. In particular, a copper recovering method of recovering copper from a copper-containing acidic waste liquid includes adding a liquid mixture of a copper-containing acidic waste liquid and an oxidizing agent to an alkaline agent solution while a pH of the alkaline agent solution to which the liquid mixture has been added is being controlled so as never to decrease to seven or lower, and by obtaining a solid material whose main component is copper oxide.
