Sphalerite grinding plant

Figure 1 – An illustration of the current Glencore-Matagami plant grinding Inadvertent activation of sphalerite by dissolution of copper ions from complex sulphide ores has been been reported in many instances (Chandra and Gerson, 2009). For the most part however, it is most

    grinding of the galena and sphalerite, the Pb content on the sphalerite surface increased with the decrease of Zn and Fe contents on the sphalerite surface. The lead ions from galena were obviously absorbed onto the sphalerite surface, while the zinc and iron ions from sphalerite were not obviously migrated to the galena surface

    Feb 01, 2019 The former original grinding and flotation operations generate a large amount of sphalerite particles in the zinc flotation feed, some of which are well liberated. Even though the particle size of these well liberated is appropriate for flotation, they are reported to the further regrinding operation together with the poorly liberated sphalerite

    Jan 01, 2021 Jan 01, 2021 Huang et al. reported that lead ions contamination on sphalerite surfaces has occurred during grinding. Basilio et al. found that the activation of sphalerite by lead ions in the plant water is the reason for the significant loss of sphalerite to lead concentrate. The surface chemical evidence provided by this study indicates that lead ions can activate not only sphalerite and pyrite but

    Apr 23, 2016 The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue. The association of the minerals and gangue requires a 65
