The Use of Polyacrylamide as a Selective Depressant in the Separation of Chalcopyrite and Galena
DownloadSpring 2013
High molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable....
