Most copper ores contain only a small percentage of copper. The remainder of the ore consists of gangue of no commercial value. Gangue from copper mining typically contains silicate minerals and oxides. In some cases these tailings have been retreated as the technology for recovering copper has improved.

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.احصل على السعر
