2005-2-1 Where the oxide lead minerals are present in appreciable amounts, it is the usual practice to float the lead sulfides first. Then, if present, the zinc sulfide is floated, followed by flotation of the lead minerals. Either sodium sulfide or sodium hydrosulfide is used as a sulfidizing agent.

2021-5-7 Some of the metals that can do the job are copper and lead. At a pH between 8-9 lead can activate sphalerite to cause it flotation. So the reason is during the flotation of the two there may be lead re dissolution from galena which may activate sphalerite to cause it flotation. It may best if you are doing bulk flotation of the two.
