Abstract

Deviations of the shape of hydrocyclone efficiency curves from the ideal S-shape have long been reported, appearing as changes in slope, or inflections. These inflections can be divided into two categories: coarse inflections, which are caused by differences in density of the minerals being separated, and fine inflections, for which there are a number of competing hypotheses concerning their cause. The existing literature addresses either the fine inflection or the coarse inflection, but no papers have reported both types of inflection occurring at once.  This paper presents hydrocyclone results from both in-plant studies and laboratory experiments that show both coarse and fine inflections and the industrial significance of both types of inflections  are discussed.
