Abstract: A novel classification approach termed the flotation classification approach based on controlling interactions between particles was introduced.It differs considerably from the conventional classification processes operating on mechanical forces.During test,the micro-bubble flotation technology was grafted onto hydro-classification.Selective aggregation and dispersion of ultrafine particles have been achieved through governing the interactions in the classification process.A series of laboratory classification tests for -44μm kaolin and -22μm quartz have been conducted on a classification column.As a result,about -10μm classifying product can be obtained from the feeds of kaolin and quartz.In addition,two criteria for the classification were set up.Finally,the theoretical model of flotation classification has been presented based on surface thermodynamics and hydrodynamics.
