Complex copper-lead-zinc bulk concentrate treatment method

The invention relates to a complex copper-lead-zinc bulk concentrate treatment method which mainly adopts a treatment method of desorption and reagent removal of sodium sulfide and activated carbon and sequential flotation of copper, zinc and lead to desorb a large number of flotation residual reagents adhered to the surface of bulk concentrate and impurity ions in ore pulp, eliminate adverse effects on separation, and improve the separation efficiency through sequential flotation of copper, zinc and lead. The problems that copper and lead are difficult to separate and the mutual content of lead and zinc in the copper concentrate is high in an existing bulk flotation re-separation process are solved, qualified lead-enriched ore can be produced, the recovery rate of metal of copper, lead and zinc is greatly increased, and harmful impurities which have great influence on smelting in concentrate products are obviously reduced. 本发明涉及一种复杂铜铅锌混合精矿处理方法，主要采用"硫化钠和活性炭解吸脱药-铜、锌、铅顺序浮选"的处理方法，解吸混合精矿表面黏附的大量浮选残留药剂和矿浆中的杂质离子，消除了
