Abstract
Processing of fines poses many problems mainly because traditional techniques do not work efficiently. In this paper, problems in fine grinding, concentration of fines and ultrafines and dewatering of slimes are reviewed along with the fundamental reasons involved. Effects of chemical additives on grinding and interference by dissolved mineral species in selective separation are examined in detail. Promising techniques considered for the beneficiation of fines include selective flocculation and agglomeration, oil and dissolved air flotation, column flotation, and magnetic, electrostatic and electrophoretic techniques. Subsidence behaviour of slimes utilized in the formulation of phenomenological models is discussed. Finally, important research opportunities in fine particle processing areas are noted.
