Method for treating suspensions of solid particles in water using amphoteric polymers |
abstract |
The invention relates to a method for treating an aqueous suspension of solid mineral particles arising from the extraction of ores, comprising the following steps: a soluble polymer is prepared in water, comprising: o at least one non-ionic monomer, selected from the group consisting of acrylamide; methacrylamide; N-monoderivatives of acrylamide; N-monoderivatives of methacrylamide; Ν,Ν-derivatives of acrylamide; Ν,Ν-derivatives of methacrylamide; acrylic esters; methacrylic esters; N-vinylformamide; and N-vinylpyrrolidone; o at least one anionic monomer representing between 10 and 70 mol%, selected from the group consisting of monomers having a carboxylic functional group and salts thereof; monomers having a sulphonic acid functional group and salts thereof; monomers having a phosphonic acid functional group and salts thereof; o at least one cationic monomer representing between 0.2 and 6 mol%, selected from the group consisting of diallyldimethylammonium chloride, methacrylamidopropyltrimethylammonium chloride and acrylamidopropyltrimethylammonium chloride; adding said soluble polymer into the water having the aqueous suspension of solid particles. This method is particularly useful for treating residues resulting from the extraction of bituminous sand. |
