摘要： 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 hydrolysis, alkali separation of indium and gallium, replacement of indium, hydrolysis of gallium, and the like. 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; pH differential copper is separated by using metal ion hydrolysis, so that costs are low; and in addition, 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.

摘要： Provided is a recovery method for a copper-indium-gallium-selenium material, mainly comprising the steps of sulfuric acid aeration leaching at a high temperature, reducing selenium with sodium sulfite, separating copper by extracting, separating indium and gallium with an alkali, replacing indium, electrolyzing gallium, etc. In the recovery method for a copper-indium-gallium-selenium material, a sulfuric acid aeration leaching means is used, thus reducing acid gas pollution; at the same time, an extraction agent for copper is used to extract copper, wherein the separating effect is good and the cost is low, and the extracted copper is directly electrolyzed so as to obtain a high-purity metal copper; moreover, an alkali is used to separate gallium, wherein realizing the separation of indium and gallium only requires the adjustment of the pH value of a solution, the separating effect is good and the obtained indium and gallium products have a relatively high purity.

摘要： Provided is a process for the comprehensive recovery of metal cobalt, ruthenium and aluminum from a waste catalyst Co-Ru/Al 2 O 3 in a Fischer-Tropsch synthesis. First, a waste catalyst is subjected to hydrocarbon removal, and reduction treatment, to effectively separate a cobalt slag in an alkali fusion step, and then the cobalt slag is subjected to the steps of acid leaching, cobalt precipitation with oxalic acid or ammonium oxalate, reduction of cobalt oxalate, dissolution of metal cobalt with nitric acid, etc., to obtain Co(N0 3 ) 2 ·6H 2 O. A ruthenate which is dissolved by steps such as alkali fusion, and leaching with deionized water, is subjected to the steps of reduction with ethanol, dissolution with concentrated hydrochloric acid, distillation under reduced pressure, etc., to obtain a β-RuCl 3 ·xH 2 O product with a high purity. Aluminum hydroxide is prepared from a meta-aluminate solution by CO 2 carbonation, by controlling the parameters such as reaction temperature, flow rate of CO 2 , pH value at the end point of the reaction, etc., and the aluminum hydroxide is calcined to obtain aluminum oxide with a product quality achieving the quality requirements of first-class aluminum oxide in the Chinese national standard. The resulting product has a high yield, wherein cobalt is ≥ 97%, ruthenium is ≥ 95%, and aluminum is ≥ 92%.
