An Atomic Force Microscopy Study of the Adsorption of Collectors on Chalcopyrite

Research output: Chapter in Book/Report/Conference proceedingChapter


The adsorption of various collectors on chalcopyrite in aqueous solutions has been studied in situ by applying an atomic force microscopy (AFM). The obtained AFM images show that the morphology of mineral surface changes correspondingly with the change of solution chemistry, such as collectors’ type and dosage, suggesting that AFM is a powerful tool for the study of the adsorption of chemicals on mineral surface in froth flotation. By comparing the AFM images obtained at different conditions, one can also conclude the effectiveness of a collector and its optimum dosage during the flotation of chalcopyrite. Based on the findings, the application of different types of collectors in chalcopyrite flotation is discussed.
