Title: Process to improve the removal of suspended solids in leached uranium ore clarification

Abstract

A process to improve suspended solids removal from leached uranium ore by filtration on a filter cloth is described comprising (a) contacting, prior to contact with the leached uranium ore, the filter cloth with an effective amount of a polymer selected from the group consisting of homopolymers of acrylamide having a molecular weight of 3,000,000 to 8,000,000 and copolymers of acrylamide and dimethyl diallyl ammonium chloride having a molecular weight of 1,000,000 to 8,000,000, containing at least 50% acrylamide and less than 50% dimethyl diallyl ammonium chloride, by weight; and (b) passing the leached uranium ore through the filter cloth, wherein the leached uranium ore contains an effective amount of an acrylamide polymer as a filtration aid.
