Flotation separation of chalcopyrite from talc using carboxymethyl chitosan as a depressant was studied. Flotation tests indicated that carboxymethyl chitosan had a selective depression effect on talc and the use of carboxymethyl chitosan as the depressant could achieve flotation separation of chalcopyrite from talc at pH 7. Adsorption studies showed that carboxymethyl chitosan only adsorbed on the surface of talc. This was the reason why carboxymethyl chitosan had high depression selectivity for talc. The zeta potential measurements and XPS analysis indicated that carboxymethyl chitosan adsorbed on the talc surface mainly through physical interaction and hydrophobic interaction may be the main driving force.
