Abstract
A method for flocculating clay minerals suspended in a liquid medium comprises adding to the liquid medium a coagulating amount of polyethylene oxide which has a reduced viscosity of from 1 to 75 in acetonitrile. Examples of clay minerals include uranium ore p slurries, phosphate slimes, and turbid waters. An additional clay mineral may be added to the suspension system such as bentonite clay, sodium or calcium bentonite. Alternatively calcium or ferric chloride may be added to aid precipitation and an antioxidant, such as a diamine derivative, can be incorporated in the polyethylene oxide.ALSO:A method for flocculating clay minerals suspended in turbid waters comprises adding to the liquid medium a coagulating amount of polyethylene oxide which has a reduced viscosity of from 1 to 75 in acetonitrile.
