Organic macromolecules are widely used as flocculant in waste water treatment and in mineral beneficiation. Their selection for beneficiation requires adsorption of these molecules through chemical interaction and hydrogen bon-ding. The factors which affect their adsorption are dis-cussed in this paper. Thermodynamic measurements of the adsorption of starch on hematite surface has shown their specificity in adsor-ption. Role of chemical complexes formed at the mineral surface has been highlighted. Computation of N-I from the adsorption isotherms at different temperatures using Clausis-Clayperon equation, in this case, is not valid because the starch molecules get adsorbed on the surface by specific (chemical) means.
