The effect of sodium hydrosulfide on molybdenite flotation

Nov 01, 2020 1. Introduction. Molybdenite, the principal mineral containing molybdenum, is closely associated with copper sulfides (Hirajima et al., 2014).The recovery of molybdenite from copper ores is usually achieved by bulk flotation to obtain a copper-molybdenum concentrate, followed by molybdenite flotation against copper sulfides in the presence of NaHS or Na 2 S (Ansari and Pawlik, 2007,

The effect of sodium hydrosulfide on molybdenite flotation

Depressing copper sulfides using sodium hydrosulfide (NaHS) in the flotation of molybdenite is a common practice. However, the effect of NaHS on the flotation of molybdenite is not clear despite a number of studies. In this study, the effect of NaHS concentrations which depressed the flotation of chalcopyrite on the flotation of molybdenite of
