The production practice of recovering lead,zinc and silver from cyanidation residue by bulk flotation process is introduced in the paper.By using the bulk flotation process of "one roughing-two scavenging-two cleaning",and using ATTA as active agent,the combination of sodium butyl xanthogenate and ethyl thiocarbamate as collector,a bulk concentrate containing 17.55% lead,27.13% zinc and 77.26 g/t silver can be produced,and the recovery rate of lead,zinc and silver is 69.25%,86.54% and 67.15%respectively.
