Graduate Theses & Non-Theses
The chalcopyrite-molybdenite (Cu-Mo) flotation industry is increasingly turning to organic depressants as suitable replacements for inorganic reagents such as NaHS due to environmental and safety concerns as well as high consumption rates of the inorganic reagents. An opportunity arises for improving, designing and synthesizing new alternative reagents. Disodium Carboxymethyl Trithiocarbonate (Orfom® D8) depressant is an organic depressant with a carboxylate group on one end and a trithiocarbonate group at the other end. Fundamental results are shown regarding the interaction of the Orfom® D8 depressant in the bulk flotation of a Cu-Mo concentrate from an operating North American mine. …
