Carboxymethyl Chitosan as a Selective Depressant in Differential Flotation of Galena and Chalcopyrite
DownloadSpring 2015
Toxic inorganic depressants are routinely used in the differential flotation of polymetallic sulfide ores and it is desirable that they be replaced with environmentally benign chemicals. Chitosan, as a natural and non-toxic polymer, has been proven to be an efficient depressant for copper sulfide...

Fall 2019
In nature, the molybdenite ores are frequently associated with copper sulfide minerals such as chalcopyrite, and the flotation separation of copper-molybdenum (Cu-Mo) sulfides largely relies on the use of toxic and hazardous depressants such as cyanides, Na2S/NaHS. It is desired to replace these...
