| titleOfInvention | A method for recovering copper and high-purity silicon powder from organic silicon waste contact body |
| abstract | The invention discloses a method for recovering copper and high-purity silicon powder from waste organosilicon contact bodies, comprising the following steps: adding waste organosilicon contact bodies, sulfuric acid solution A and adjusting agent into an air flotation mechanical stirring and coupling leaching tank, and then passing through Enter the air and mechanically stir the oxidative leaching to obtain the leaching slurry; separate the leaching slurry from solid and liquid to obtain the copper-containing leaching solution and the leaching slag, and wash the leaching slag, press-filter and neutralize to obtain silicon powder; adjust the pH of the copper-containing leaching solution to 1.5 ~2.0, then add copper extractant to the copper-containing leaching solution for extraction, and separate to obtain copper-extracted residual liquid and copper-containing organic phase; add sulfuric acid solution B to the copper-containing organic phase for back extraction to obtain back-extracted copper sulfate solution and regeneration. Organic phase; copper electrowinning is performed on the back-extracted copper sulfate solution to obtain cathode copper. The whole process of the invention has mild reaction conditions, environmental protection for equipment, low energy consumption and wide applicability, the recovery rates of copper and silicon powder are both over 95%, the purity of cathode copper is over 99.95%, and the purity of silicon powder is over 98%. . |
