Donald Allen AS: Ciba Specialty Chemicals Water Treatments Limited The aqueous clay waste formed during a phosphate or other mineral recovery processes is flocculated in a well which is generally formed in a sedimentation lagoon, the supernatant is taken from the top of well and is recycled to the main flotation or other separation process (generally after running across sediment in the lagoon) and the thickened sediment which is formed in the well is pumped from the base of the well to one or more final lagoons where it is converted to a solid sediment by sedimentation and evaporation.
