| titleOfInvention | A method for separating and recovering valuable metals from electroplating sludge using combined chlorinating agents |
| abstract | The invention discloses a method for separating and recovering valuable metals from electroplating sludge by adopting a combined chlorinating agent. First, drying and pulverizing electroplating sludge powder is uniformly mixed with a combined chlorinating agent, an additive and a cosolvent, and then placed in a tubular In the furnace, the chlorination roasting is carried out under the atmosphere of the protective gas after being evacuated. The main metals chromium, nickel and copper contained in the electroplating sludge are converted into corresponding metal chlorides by adding a chlorinating agent for roasting. Due to the difference in the volatilization temperature of the three metal chlorides, the three-stage constant temperature roasting at different temperatures makes the generated metal chlorides volatilize at the corresponding roasting temperature and collect the soot to realize the three metals of chromium, nickel and copper in the electroplating sludge. The cascade separation recycling. |
