The polymetallic ore contains minerals such as molybdenite, pyrite, rutile, ilmenite and magnetite, sphalerite, chalcopyrite, galena, limonite, hematite, spot copper, nickel pyrite, arsenopyrite, scheelite. The gangue minerals mainly include quartz, biotite, muscovite, potassium feldspar, a small amount of sodium feldspar, grossular, calcite, fluorite, apatite, sphene, chlorite, sericite, kaolinite, and so on.

In this paper, bulk flotation followed by separation was investigated to concentrate purified molybdenite product from Jinduicheng molybdenum ores(Shanxi province, China). The bench scale tests mainly focussed on separation of molybdenite from other sulfide minerals using the new type of depressants.The effect of each single depressant, including organic depressant-modified dextrin(MD), P-Nokes reagent(PN) and sodium trithiocarbonate(ST), and their mixtures on galena, chalcopyrite and other sulfide ores, was examined in turn by changing the concentrations used in cleaner flotation tests.
