filtration of concentrate after flotation

The results indicated that the improvement in gold extraction after filtration and oxidation of the original pulp was due to partial removal of the flotation reagents, and illustrates the detrimental effects that residual flotation reagents can have on the extraction of gold by cyanidation of a flotation concentration.

Abstract. Laboratory data are presented on the degradation of polyoxyethylene during storage and under mechanical and chemical action. Provided the physico-chemical properties of the polymer are considered and conditions are adjusted to minimize its degradation during solution preparation, POE can be used as a highly effective flocculant for the commercial filtration of flotation concentrate.
