Flocculation in Mineral Processing | SpringerLink
Abstract. Flocculation is a characteristic property of colloidal dispersions. The typical classical sol contained sub-microscopic dispersed particles which would pass freely through ordinary filter-paper, and were too small to be resolved by any transmission optical microscope. Consequently, an arbitrary size limit of 0.1 μm could be defined as the upper size boundary of the colloidal range.
