| titleOfInvention | Recycling treatment method for ash of copper smelting furnace |
| abstract | The invention discloses a resource treatment method of soot of a copper smelting furnace. Separating lead copper from tin, arsenic, zinc and antimony in the ash by high-temperature alkali cooking; introducing hydrogen sulfide into the obtained filtrate to precipitate tin, arsenic and antimony, then continuously introducing hydrogen sulfide to precipitate zinc, adding sulfuric acid into the zinc precipitate to dissolve, and then concentrating and crystallizing to obtain industrial pure zinc sulfate; adding lead and copper into a hydrochloric acid solution, then adding sodium chlorate, and cooling the obtained solution to obtain lead chloride filter residue and copper chloride filtrate; dissolving the tin-arsenic-antimony filter residue in hydrochloric acid to obtain an antimony-containing solution, adding an extracting agent into the antimony-containing solution for extraction, performing back extraction by using p-ammonia water, concentrating and crystallizing the obtained back extraction solution to obtain antimony chloride, adding a sodium sulfide solution into the obtained fifth filter residue for reaction, and then filtering to obtain a tin-containing filtrate and arsenic sulfide residue. The method can realize separation and recovery of valuable metals in the soot, has high recovery rate, high purity of the finally obtained product, low cost and short process, and simultaneously recovers most of by-products in the product. |
