Zusammenfassung:	A process for the froth flotation of calcium phosphatecontaining minerals is provided which comprises carrying out the flotation in the presence of an amphoteric flotation agent having the general formula: wherein: R is a hydrocarbon group having from about seven to about twenty-four carbon atoms; A is an oxyalkylene group having from two to about four carbon atoms; R1 is selected from the group consisting of hydrogen and hydrocarbon groups having from one to about four carbon atoms; Y-is selected from the group consisting of COO- and SO3-; n is a number from 0 to 1; p is a number from 0 to 5; q is a number from 1 to 2; and salts thereof.
