    摘要: The invention relates to separation of submicron particles of illite mineral from illite clay. There is offered a method for separation of submicron particles of illite mineral from illite clay, comprising: (i) mixing of illite clay in dispersant aqueous solution or mixing of illite clay and dispersant in water; (ii) sedimentation of the resultant suspension; (iii) addition of a coagulant composition formed from a saturated solution of hydrazine hydrogen chloride, hydrochloride acid and acetone to the resultant suspension; (iv) separation of submicron particles of illite mineral from the solution, containing the potential dispersant and coagulant residues. There is also offered a coagulant adapted for use in separation of submicron particles of illite mineral from illite clay is offered, the coagulant being formed from a saturated solution of hydrazine hydrogen chloride, hydrochloride acid and acetone in weight ratio from 1:1:4 to 1:1:6.

    摘要: 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.
