Depression of lead activated sphalerite by pyrite via
15/06/2020· Fig. 4 shows the results of single mineral flotation of sphalerite with and without 5 ppm of Pb 2+. Only ~15 of Zn was recovered as froth products without Pb 2+, but in the presence of Pb 2+, recovery of Zn dramatically increased to ~80 . This could be attributed to lead activation of sphalerite consistent with Eq. and the reports of other authors. Download : Download high res image 65KB
