In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation minerals. Therefore the standard Cu-Pb-Zn flotation practice involves an initial flotation of a Cu-Pb bulk concentrate followed by two parallel circuit stages of copper-lead separation and separate zinc flotation from the bulk flotation tails.
