چکیده انگلیسی
Both the heat of adsorption and microflotation recoveries increased with increasing collector chain length for xanthate homologues on all mineral types. There was a positive linear correlation between the heats of adsorption and microflotation recoveries. However, this relationship was not sustained for collectors with different ligand types. The heat of adsorption of diethyl-DTC was always higher than that of diethyl-DTP for all the minerals. In fact, diethyl-DTP barely interacted with any of the sulphide minerals although it produced unexpectedly high chalcopyrite recoveries. It was found that the heat of adsorption is not a robust indicator of hydrophobicity for collectors of different ligand types. However, for collectors of the same ligand type, but differing alkyl chain lengths, it is a strong predictor of hydrophobicity.
