Abstract: Process of froth flotation of oxide minerals which comprises using at least one of the following collector agents 1. MIXED SALTS OF AMMONIUM AND AMINES OF THE FORMULA: X(COONH4)2 (COOH.NR''R''''R'''''')2 2. ester-sulfonates of the formula: HX(COOR'')(COOR'''')(COOR'''''')(COOR'''''''')(SO3M) 3. ester amine salt sulfonates of the formula: HX(COOR)2(COOH.NR''R''''R'''''')2(SO3M) 4. sulfonates of mixed salts of ammonium and amines of the formula: HX(COONH4)2(COOH.NR''R''''R'''''')2(SO3M) in these formulae, X representing the hydrocarbon radical of the acid obtained by controlled pyrolysis of calcium citrate and acidification of the obtained pyrolysate; R being a C1-C20 alkyl radical; R'', R'''', R'''''' and R'''''''' being each hydrogen, C1-C20 alkyl, cycloalkyl, aralkyl, alkaryl or aryl, at least one of R'', R'''', R'''''' and R'''''''' being other than hydrogen and M being sodium, potassium or ammonium.
