摘要

•Chalcopyrite can be separated from sphalerite using DTC-CTS as depressant.•Depression performance of DTC-CTS depends strictly on its dosage.•DTC-CTS blocks the subsequent adsorption of butyl xanthate on sphalerite surface.•DTC-CTS has little effect on the adsorption of butyl xanthate on chalcopyrite.
