Beschreibung
Zusammenfassung:	The present invention relates to a process to treat siliceous non-sulfidic ores with a collector composition that comprises a phosphate compound of the formula (I) wherein R is linear or branched, saturated or unsaturated hydrocarbon group containing 1 to 24 carbon atoms that, A is an alkylene oxide unit; Y is H, Na, K or an ammonium or alkylated ammonium, n is 1 - 3, p is 0 - 25, X is chosen from the same groups as R-Ap- or Y, to a collector composition containing the phosphate compound of the formula I as a primary collector in combination with a secondary collector and to a pulp composition containing the phosphate compound of the formula (I).
