| titleOfInvention | Method for recovering valued metals from zinc anode sludge |
| abstract | The invention provides a method for recovering valued metals from zinc anode sludge, which comprises the following steps of: A, selective leaching: immersing milled zinc anode sludge into sulfuric acid, leaching, filtering to obtain zinc sulfate solution and pickling slag, and recovering zinc through a zinc sulfate solution zinc feeding system; B, reduction leaching: adding the pickling slag into the sulfuric acid, then adding oxalic acid, filtering to obtain manganese sulfate solution and lead and silver leaching slag after reaction, and recovering lead and silver through a lead and silver leaching slag lead returning system; C, purifying: firstly adding ammonia water into the manganese sulfate solution, then adding (NH4)2S and NH4F, and filtering to obtain purified liquor and purified slag after reaction; and D, synthetizing: synthetizing the purified liquor, and drying to obtain a manganese product. According to the method provided by the invention, the recovery rate of zinc is more than 94 percent, the recovery rate of manganese is more than 91 percent, the recovery rate of lead is more than 95 percent, and the recovery rate of silver is more than 97 percent. |
