SELECTIVE FLOTATION OF GALENA AND SPHALERITE AT

2014-12-10 · flotation recoveries of galena and sphalerite are discussed in Chapter 5. The flotation results indicate that high dosages of xanthate collector of long chain length such as PNBX are detrimental to the flotation selectivity between galena and sphalerite. As expected, Cu(II) is a much stronger activator for sphalerite than Pb(II) ions. It is also

Effect of Grinding Media on Galena Flotation | SpringerLink

Grinding with steel media adversely affects the flotation response of galena. Electrochemical measurements, flotation tests, and examinations were employed to identify interactions between galena and mild steel. Iron oxide, hydroxide, or sulfate species that formed on the galena surface upon contact with mild steel decreased its floatability, with the time of contact and aeration condition ...
