| titleOfInvention | Comprehensive utilization method of zinc roasting oxidation waste residue |
| abstract | The invention discloses a comprehensive utilization method of zinc roasting oxidation waste residue, which comprises the following steps: (1) copper and silver flotation: grinding the zinc slag, adding a capture agent and second oil for flotation, wherein the flotation comprises primary roughing, primary fine concentration and twice scavenging to obtain flotation concentrate and tailings A; (2) magnetic separation: levigating the flotation concentrate, and then carrying out magnetic separation by using a high-gradient pulse strong magnetic separator to remove organic carbon in the flotation concentrate, wherein the magnetic field intensity is 1T, so as to obtain magnetic separation concentrate and tailings B; (3) roasting and acid leaching: and (3) roasting the magnetic concentrate, ultra-finely grinding, leaching with sulfuric acid, filtering and washing to obtain a pregnant solution, a washing solution and leaching residues, recovering noble metals from the pregnant solution, taking tailings A and tailings B as cement ingredients, and taking the leaching residues as pyrometallurgical raw materials. The method has the advantages of high metal recovery rate, low cost, realization of tailing-free comprehensive recycling and contribution to the promotion of zinc slag recycling technology, and tailings generated in the process are ingredients of cement, and leaching slag is used as a raw material for pyrometallurgy and can be directly recycled. |
