CARBOHYDRATE AND ACRYLAMIDE POLYMERS USEFUL AS FLOCCULANTS IN PROCESS WATER OBTAINED FROM AN OIL-SANDS MINING OPERATION

摘要

The present invention relates to a method of producing flocculation in a soil/water mixture, said method comprising: applying to or including in said mixture, a composition comprising an activated starch, a maleamate-modified starch, or a combination thereof, and an acrylamide polymer, wherein said maleamate-modified starch comprises groups of the form -CH(COO - M + )CH 2 C(O)NH 2 , where M + represents hydrogen or a cation, linked to said starch via ether linkages.
