Abstract: Abstract Galactomannan (GM) was used as depressant to facilitate the separation of pyrite from talcum. Compared with common depressant dextrin, GM not only possessed higher selectivity, but also GM was consumed approximately 87% lower than… read more here.

Abstract: ABSTRACT Four oxidants, NaClO, KMnO4, K2Cr2O7, and H2O2, were used to promote the flotation separation of pyrite (FeS2) from arsenopyrite (FeAsS). Ore flotation results indicate that H2O2 has the best selectivity for the As-S separation.… read more here.
