The present invention relates to the use of a polyquaternary polymer obtainable by reacting i) a dialkylamine having the structure R1R2NH, where R1 and R2independently are hydrocarbyl groups having 1 -3 carbon atoms; ii) a difunctional compound selected from the group consisting of epihalohydrins, diepoxides, precursors of epihalohydrins and epoxides which under alkaline conditions are readily converted into the corresponding epoxy compounds, and mixtures thereof; and iii) optionally a polyfunctional amine selected from the group consisting of ammonia, primary amines, alkylenediamines having 2-6 carbon atoms, and polyalkylenepolyamines having the structure H2N-[R3-N(R4)]y-R3-NH2, where y is an integer from 1 to 5, R3 is an alkylene radical having 2 to 6 carbon atoms, and R4 is selected from the group consisting of hydrogen, a hydrocarbyl group having 1 - 3 carbon atoms, and an ω-aminoalkyl group having 2 to 6 carbon atoms; as a depressant in a method for froth flotation of potash ores.
