| titleOfInvention | Copper smelting byproduct co-processing technology |
| abstract | The invention discloses a synergistic treatment process for copper smelting byproducts, which is characterized in that the copper smelting byproducts are low-concentration SO 2 Flue gas, smoke dust, waste acid and high-concentration SO 2 The flue gas is treated cooperatively by treating low-concentration SO 2 Three-stage desulfurization of flue gas, two-time heating oxidation leaching, high-temperature system volatilization, recovery of valuable metals and high-concentration SO 2 Heating flue gas, reducing, precipitating, dearsenizing, vulcanizing, precipitating copper, evaporating, concentrating, crystallizing and the like to carry out synergistic treatment on the copper smelting by-products; the process of the invention can reduce the concentration of SO 2 SO in flue gas 2 Most of the arsenic is removed, the using amount of a desulfurizer is small, the cost is saved, the leaching rate of metals such As arsenic, copper, zinc and the like is high, the arsenic leached from the smoke dust and the waste acid stock solution is easy to be reduced and separated out, and the arsenic is used As 2 O 3 The method has the advantages of high recovery rate of copper and zinc, consumption of a large amount of waste acid stock solution, no hazardous waste residue, comprehensive treatment of tail gas and good environmental protection effect. |
