Oxide Zinc And Lead Mineral Flotation

  • Flotation of zinc and lead oxide minerals from Olkusz

    secondary carbonate minerals of zinc and lead takes place. Due to the similarity of surface properties of carbonate minerals of zinc and lead to the surrounding waste rock, which is mostly dolomite, their flotation has not yet been sufficiently resolved. So far, the studies have shown that the only practical flotation method of oxide ore of Zn-Pb

  • Flotation of Aladagˇ oxide lead–zinc ores ScienceDirect

    2005-2-1 · Where the oxide lead minerals are present in appreciable amounts, it is the usual practice to float the lead sulfides first. Then, if present, the zinc sulfide is floated, followed by flotation of the lead minerals. Either sodium sulfide or sodium hydrosulfide is used as a sulfidizing agent.
