Surface Properties Of Coppersulfide Minerals With Sodium

Sep 01, 2020 The surface properties of slightly oxidized chalcocite, bornite, and chalcopyrite with sodium hydrosulfide NaHS treatment were investigated by solid analyses of X-ray photoelectron spectroscopy, solution analyses, and zeta potential measurements. NaHS is known as a flotation activator for copper-oxide minerals by sulfurizing their surfaces.

Surface Properties Of Coppersulfide Minerals With Sodium

NaHS sulfurizes oxidized copper species, but not oxidized iron species. Oxidized iron species dissolve as the complex ion then reprecipitates as ferric oxide. pH and NaHS concentration affect Fe 2 O 3 reprecipitation onto bornite and chalcopyrite. Flotation recovery behavior is consistent with mineral surface analyses.
