Fig 9 Fig 10 show the effect of concentration of the mixed depressant and pH on the separation of calcite from pyrite At around the depressant concentration of × 10 −4 M the two minerals were almost perfectly separated and the separation efficiency was at the maximum The optimum dosage of the depressant was times higher than in
Flotation represents a prevalent technique for the separation of chalcopyrite and pyrite that relies on distinctions in the physical and chemical characteristics of mineral surfaces Zhang et al 2023 Cai et al 2022 Cai et al 2022 Liu et al 2017 To secure a superior copper concentrate numerous depressants are commonly employed to impede pyrite
The flotation separation of Cu Fe sulfide minerals at low alkalinity can be achieved using selective depressants In the flotation system of Cu Fe sulfide minerals depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector This review summarizes the advances in
