Details >Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
Details >Oxidized zinc minerals are floated after sulfides, as well as oxidized lead minerals. The flotation of oxidized lead-zinc minerals after preliminary sulphidization with sulfhydryl collectors is currently the effective way to recover Pb and or Zn bearing minerals from oxidized and mixed ores.
Details >Galena has good floatability. In most lead-zinc mines, zinc is higher than lead. Most of the lead-zinc sulfide mine uses preferential flotation technology, “floating lead and zinc-suppressing”, which is often reasonable both technically and economically. 2 Lead-zinc oxide ore.
