The mechanism of the Cu2+ enriching process by chitosan as a flocculant chelating compound has been studied through morphological observation by AFM in noncontact mode. The colloid chitosan-Cu2+ aggregates were found to be regularly aligned. It could be further condensed by dehydration to from a more regular cyclic shape in small particle units. The process appears similar to that resulted by screw winding of particles. The higher concentrated sample is a regular disc-like shape. The range of disc diameters was between 35~50 μm.
