| titleOfInvention | Method for preparing thallous chloride using lead zinc ore smelting wastewater as raw material |
| abstract | The invention relates to a method for preparing thallous chloride using lead zinc ore smelting wastewater as a raw material. The method comprises the following steps: (1) getting lead zinc ore smelting wastewater, and adding lead zinc ore smelting waste residue to lead zinc ore smelting wastewater in a ratio of 1: 500 (g/ml), agitating for 2 hours, adding lime to adjust pH (Power of Hydrogen) to be 8 to 9, precipitating, and collecting the bottom mud; (2) drying and crushing the bottom mud to obtain bottom mud powder, adding lead zinc ore smelting wastewater to the bottom mud powder in a ratio 5: 1 (g/ml), agitating for 1 hour, then adding sulfuric acid to adjust pH to be 1, and filtering to obtain thallium extracting liquid; (3) adding chloridion-containing wastewater to the thallium extracting liquid in a volume ratio of 1: 1 to obtain a mixed solution, then supplementing sodium chloride until chloridion in mixed solution is at concentration not less than 0.5mol/L, precipitating, and collecting the precipitate; and (4) drying the collected precipitate to obtain the TlCl (thallous chloride). The method has the advantages of being simple in process, and low in cost, and realizes the treatment of wastes with processes of wastes against one another. |
