  Sulfidation roasting of low grade lead–zinc oxide ore with elemental ...

  201061 · They found that the optimum flotation of sulfide-treated cerussite occurred when the dose of Na 2 S set the pulp potential in the range from −100 mV to 150 mV with a saturated calomel electrode. Onal et al. (2005) investigated the flotation and gravity separation of Aladag oxide lead–zinc ores which contained 10.2% Pb and 11% Zn.

  Zeta potentials in the flotation of oxide and silicate minerals

  2005630 · Abstract. Adsorption of collectors and modifying reagents in the flotation of oxide and silicate minerals is controlled by the electrical double layer at the mineral–water interface. In systems where the collector is physically adsorbed, flotation with anionic or cationic collectors depends on the mineral surface being charged oppositely.
