The case of small ore cu zn pb setup

copperleadzinc orestherefore the standard cupbzn flotation practice involves an initial flotation of a cupb bulk concentrate followed by two parallel circuit stages of copperlead separation and separate zinc flotation from the bulk flotation tails. heavy metal pollution caused by smallscale metal ore mining the mean contents of cu, zn, as, cd, and pb in the surface soils of local farmlands were up to 7 times higher than the corresponding background values, and results of multivariate statistical analysis clearly indicate that cu, zn, cd, and pb were largely contributed by the mining activities. zehang sun, xiande xie, ping wang, yuanan hu, hefa cheng 96 2018i n.t.s.: m'vein, returned an assay of 22.42 g/t au, 447.3 ag, 1.5% pb, .96% zn. the average assay values are in the range of: 12 g/t au, 3060 g/t ag, and 6% combined pbzn. the geochemical talus fines survey outlined a broad, strong pbznag anomaly and a moderate to strong cuau anomaly. scandinavian caledonide metallogeny in a plate tectonic this setting is considered to have been host to two characteristic types of strataboundstratiform ores: massive to disseminated znpbcu and cuzn sulphides in sedimentary and mixed sedimentaryvolcanic lithologies with original ore reserves up to 56 mt (bleikvassli, mofjellet)and numerous, laterally extensive, magnetitehematite deposits experiment 9 electrochemistry i galvanic cellzn(s) + cu2+(aq) zn2+(aq) + cu(s) (4) the electrons are not shown because they are neither reactants nor products but have simply been transferred from one species to another (from zn to cu2+ in this case). in this redox reaction, the zn(s) is referred to as the reducing agent because it causes the cu2+ to be reduced to cu. scandinavian caledonide metallogeny in a plate tectonic this setting is considered to have been host to two characteristic types of strataboundstratiform ores: massive to disseminated znpbcu and cuzn sulphides in sedimentary and mixed sedimentaryvolcanic lithologies with original ore reserves up to 56 mt (bleikvassli, mofjellet)and numerous, laterally extensive, magnetitehematite deposits
