  Beneficiation of Oxidized Lead-Zinc Ores by Flotation Using …

  20191227 · This study presents the recovery of oxide-carbonate lead-zinc ores using different chemical reagents under different test conditions by flotation. The run-of-mine oxide-carbonate Pb-Zn ore contains 9.05% Pb and 11.97% Zn with a major mineralization of smithsonite and cerussite. First experimental work was grinding tests to reduce -106 μm …

  Hydrothermal Sulfidation and Flotation of Oxidized Zinc-Lead Ore

  2014211 · The sample with smithsonite and cerussite as the main valuable metal minerals is a carbonate-hosted lead-zinc ore in the current study. Hydrothermal sulfidation of oxidized zinc-lead ore was carried out with a particle size of 74 to 58 μm and the mole ratio of sulfur and zinc of 2.0 at 453 K (180 °C) for 240 minutes, and 73 pct zinc and 86 pct …

  Fluorite Ore Flotation Methods & Influencing Factors

  6  · The flotation of barite-type fluorite ore generally first adjusts the pH value of the ore pulp through the process of mixed flotation and Na2CO3, and uses oleic acid and water glass as collectors and inhibitors respectively to obtain the fluorite and barite. The concentrates are mixed and flotation is used to barite separation.
