Anode slime Kaldo furnace smelting flue gas treatment method

The invention discloses an anode mud pyrometallurgy flue gas treatment method. The anode slime is subjected to pressure leaching to obtain a pressurized decoppered material, the pressurized decoppered material is dried and then is matched with a reagent for slagging and smelting of the gold-silver alloy, main flue gas generated by smelting enters a selenium recovery system through an uptake flue for precious metal recovery and selenium recovery, flue gas escaping in the smelting process enters an environment-friendly absorption system, and the environment-friendly absorption system is used for absorbing the gold-silver alloy. A cloth bag is adopted for dust collection and recovery of precious metal, flue gas of a main system and flue gas of an environment-friendly system are converged and then merged into a copper smelting flue gas system, cooling of a turbulent washing tower, cooling of the turbulent washing tower, dust collection of a washing tower, cooling of a cooling tower, dust removal of an electric de
