The effect on the surface properties and floatability of chalcocite and enargite after oxidative treatment with hydrogen peroxide (H2O2) in the presence and absence of potassium amylxanthate (PAX) as a collector was studied. In this research, flotation tests were carried out on mixed and individual minerals. Oxidative treatment with hydrogen peroxide had a negative effect on the floatability of chalcocite and enargite. PAX adsorption analysis shows that enargite adsorbs PAX faster than chalcocite. Moreover, Fourier transform infrared spectroscopy analysis shows that PAX was adsorbed in the form of copper amylxanthate on chalcocite and enargite surfaces. In addition, dixanthogen was adsorbed on the surface of enargite, and the surface of chalcocite was more oxidized compared to enargite. Flotation of mixed minerals shows that the floatability of chalcocite was more suppressed compared to enargite after treatment with PAX and H2O2. This result demonstrates the possibility of separating chalcocite and enargite by treating PAX and H2O2 at pH 9.
