flotation process for recovery of lead

  • Using a New Bulk Flotation Process to Enhance the Recovery

    Many tests work have been done to develop a new bulk flotation process to enhance the Pb and Zn recovery. Flotation results of the closed circuit test indicate that the Pb and Zn recovery from the new bulk flotation process can be increase by 10 per cent and 2 per cent, respectively, which makes very considerable benefit for the mine.

  • Effects of particle size on flotation performance in the

    Model 1 presents a more excellent fit to the lead recovery as a function of flotation time in the separation flotation process, and the R 2 values obtained from the model 1 with various size fractions were all gt;0.99, which were the biggest among the investigated models. Therefore, the model 1 was considered to be the most reasonable model for fitting the lead recovery in the separation flotation process.

  • Lead Zinc ores Danafloat Home

    Flotation separation and recovery of lead and zinc concentrates from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved quite effectively. Silver often provides highly significant economic value, if not the greatest value, with the silver most often associated with the galena mineralization which is fortuitous since smelters pay more for silver in lead vs. zinc concentrates.
