Title: Comparative assessment of the breakdown of high-molecular flocculants

Abstract

In recent years, a much wider range of water-soluble polymer flocculants has come into use to accelerate the clarification of coal and clay-coal suspensions, in which the solid phase comprises flotation tailings or slurry. The major distinguishing feature in this development has been the switch from gel-type flocculants to granular or powder types. Difficulties arise in the use of flocculants, from the relative ease with which they break down during storage or solution preparation. Different polymers behave differently under the same mechanical or chemical forces. Failure to appreciate this often leads to erroneous conclusions regarding the specific effectiveness of various flocculants. Breakdown data are described on various high-molecular flocculants, showing that the major factors that influence the breakdown of polyoxyethylene (POE) can be traced in other polymer flocculants as well.
