  • Copper Lead Zinc ores Danafloat

    Copper Lead Zinc ores. The Cu Pb Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead minerals tend to

  • Lead Zinc ores Danafloat Home

    While pyrite is fairly easy to depress with lime, pyrrhotite is more difficult to depress. An alternative to metabisulphide depression is to aerate the slurry which, if the pyrrhotite is reactive, can render this iron sulphide less floatable. In cases of greater iron sulphide depression challenges, the zinc concentrate can be cleaned by reverse flotation of
