Pennetta de Oliveira, Leonardo
Bitumen has been extensively extracted from oil sands through the Clark Hot Water Extraction (CHWE) process. This extraction process uses hot water and alkaline conditions to remove bitumen from oil sands ores. The tailings produced by this process are mixtures of sand, clays, residual bitumen,...

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....
