copolymer, and processes for treating an aqueous slurry and for producing a copolymer. |
| abstract |
A multivalent cation containing copolymer derived from one or more ethylenically unsaturated acids is described. the copolymer has the following characteristics: (a) an intrinsic viscosity of at least about 3 dl / g when measured in 1 m of nacl solution at 25 ° c; (b) the copolymer is derived from a monomer mixture comprising an ethylenically unsaturated acid and at least one comonomer, the ethylenically unsaturated acid present in an amount ranging from about% to about 65% by weight; and (c) a residual comonomer content is less than 1000 ppm when the comonomer is an acrylamide. The copolymer, inter alia, is useful as a flocculant for treating an aqueous slurry comprising particulate material, preferably tailings from a mining operation. |
