[Display omitted] •Copper ions severely deteriorate the floatability of chalcopyrite and molybdenite.•The adsorption of CuOH+ and Cu(OH)2 provide more reaction sites for depressants.•Cu2S is identified as the primary product during the inhibition process.•The similar floatability makes it difficult...
