| description | The invention discloses a method for resource utilization of lead and zinc smelting waste. Firstly, lead and zinc smelting waste is subjected to magnetic separation after crushing and ball milling, and iron concentrate and magnetic separation tailings are obtained; then, after ultrasonic activation, the magnetic separation tailings are subjected to bulk flotation, mixed concentrate and flotation tailings are obtained, a newly-developed collector YB-1 is adopted at the time of flotation, and the lead and zinc flotation effect is good; then, the mixed concentrate is subjected to high-temperaturetreatment after microwave activation, valuable metals such as lead, zinc, silver and indium in the mixed concentrate are volatilized to form smoke dust, after collection through a bag collector, lead-zinc concentrate is obtained, the tailings are discharged from the tail portion of a furnace, and mineral powder is obtained after water quenching treatment. The method achieves comprehensive recycling of the lead and zinc s |
