Flocculation of Fine Particles With Polyethylene Oxide: A Proposed Mechanism.
Trans Soc Min Eng AIME 1987 280:2115-2117
This paper describes a technique for dewatering phosphatic clay waste to recover metals and other minerals by flocculating it with polyethylene oxide (peo). Results showed that peo was far superior to polyacrylamide polymers for this type of dewatering, as peo causes the formation of a stronger bond with the exchange ions, causing the clay to remain stable and resist reslurrying more efficiently than material flocculated with polyacrylamide.
