Abstract
Test flotation of pyrite used potassium butyl xanthate and sodium butyl dithiophosphate as collectors. The study of the influence exerted by the nature of a sulfhydryl collector on the flotation ability of pyrite included pyrite samples -74+44 µm in size. The findings on froth flotation of pyrite with addition of one or two traditional sulfhydryl collectors which display similar collecting action in treatment of pyrite at pH 8 are described. From the analysis of the kinetic curves of pyrite flotation, a new approach to the assessment of flotation activity of thiol collectors is proposed.
