| 摘 要： | In this research it was shown that mineral surface metal-lic sites played a decisive role in carborymethyl cellulose(CMC) adsorp-tion, and surface hydrophobicity alone did not have significant effects.Both the carboxymethyl groups and the hydroxyl groups of the CMC par-ticipated in the interaction with mineral surface,with the carboxymethylgroups interacting with metal and metal hydroxyl species, and hydroxylgroups interacting with metal hydroxide species,respectively.
