  • Geochemical modelling of a Zn-Pb skarns Constraints from

    The analyses measured comparable concentrations of Zn and Pb though the deposit is very Zn-rich (8 ) relative to Pb (0.5 ). This inconsistency can be explained invoking a different behaviour of Zn and Pb in response to changes in the physical-chemical conditions which led to Zn precipitation as sphalerite while Pb remained mostly soluble.

  • Lime use and functionality in sulphide mineral flotation

    For treating such a new ore bulk Cu-Pb flotation followed by Zn flotation has been recommended (Sehlotho et al. 2018). An example of a sequential Cu-Pb-Zn flowsheet is given in Fig. 14 . A first flotation stage is carried out at low pH (pH 6) in which the copper sulphide is floated while both galena and sphalerite are depressed.

  • Sequential Copper–Lead–Zinc Flotation

    To improve the selectivity between copper and lead a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased particularly for copper and lead. With this process copper was recovered first with MBS depression of lead zinc and
