International Journal of Mining Science and TechnologyA novel small molecule depressant (M-DEP) was used to separate chalcopyrite and molybdenite via flotation. The results showed that M-DEP had an excellent selective depression on molybdenite, while had little effect on the flotation of chalcopyrite.

International Journal of Mining Science and Technology, 2023 Organic depressants have low selectivity in separating molybdenite and talc because their metal sites lack activity for organics chemisorption. In this study, surface modification by copper sulfate was used to induce the differential adsorption of pectin
