A method for recycling copper indium gallium selenium materials comprises the steps of leaching by using sulfuric acid and hydrogen peroxide, reduction of selenium by using sulfur dioxide, separation of copper by using cuprous ammine complexation, alkali separation of indium and gallium, replacement of indium, hydrolysis of gallium, and the like. In the recycling method, leaching is carried out by using sulfuric acid in cooperation with hydrogen peroxide, so that the leaching rate is greatly improved, and acid gas pollution is reduced; in addition, copper is separated by using cuprous ammine complexation, deposition is not generated, metal ions can be well separated;and in another aspect, in the method, alkali separation of gallium is carried out, separation between indium and gallium can be implemented by merely adjusting the PH of a solution, the separation effect is good, the purities of obtained indium and gallium products are high.
