FIELD: chemistry.
SUBSTANCE: invention relates to a method of treating siliceous non-sulphide ores, said method comprising adding a collector composition which contains a phosphate compound of formula I, in which R denotes a linear or branched, saturated or unsaturated hydrocarbon group containing 8 to 24 carbon atoms, A is an alkylene oxide link, Y is H, Na, K, ammonium or alkylated ammonium, n = 1–3, p = 0–25, X is selected from the same groups as RAp or Y, or where R denotes a linear or branched, saturated or unsaturated hydrocarbon group containing 1–12 carbon atoms, and there is at least one link A, which is a propylene oxide link. Invention also relates to composition and pulp.
EFFECT: use of the proposed invention ensures required degree of extraction of the desired product from ore and improved extraction and selectivity.
