For instance, in the case of galena we obtained for a very small galena fragment of 100 μm side dimension an exergy of 1902 J/kg and a comminution exergy cost of 4040 kJ/kg When applying Eq 1 for the same galena mineral we obtain 82 kJ/kg for the concentration exergy, ie ∼4000 times less than the comminution exergyThe problem of treating oxidized leadzinc ores for the production of highgrade 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 leadzinc carbonate ore in a mixed siliceouslime carbonate gangue The association of the minerals and gangue requires a 65 meshGalena Sphalerite Flotation & Separation Method
