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.

2.1 Froth flotation process. Froth flotation is extensively used to enrich sulfide minerals (galena, chalcopyrite, sphalerite, molybdenite, and pentlandite) as well as non-sulfides such as phosphate minerals, iron ores, and fine coal [1, 2].The mineral ore is ground to fine particles of typically 10 to 100µm in diameter and mixed with water to …
A concentrate with 5.51% Pb could be obtained with 33.91% recovery and most of the lead remained as tailings. The addition of 1000 g/ton ZnSO 4 could not prevent zinc flotation as 25.01% of zinc was reported into Pb concentrate. Önal et al. found that ZnSO 4 had no depression effect on oxidized zinc minerals in lead flotation circuit. Very ...
A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more …
