The invention relates to a method for recovering valuable metals from copper anode mud flotation tailings and belongs to the technical field of thermometallurgy. The method comprises: firstly, performing retailoring on the copper anode mud flotation tailings to obtain a reduction product, and then performing oxidative blowing on the reduction product to obtain rich lead and arsenic and antimony containing soot; first-stage low-temperature vacuum distillation: performing primary low-temperature vacuum distillation on the obtained rich lead under the conditions of a temperature of 400-700 DEG C and a pressure of 1-100Pa for 1-3h, thereby obtaining secondary rich lead and a selenium-tellurium alloy; and second-stage high-temperature vacuum distillation: performing primary high-temperature vacuum distillation on the obtained secondary rich lead under the conditions of a temperature of 800-1200 DEG C and a pressure of 1-100Pa for 1-3h, thereby obtaining a lead-bismuth and a copper-gold-silver alloy. The method for recovering valuable metals from copper anode mud flotation tailings is safe and controllable in whole process flow, simple and convenient to operate, simple in equipment needed, free from three-waste emissions, and environment-friendly.
