【Abstract】 This papers study on flotation of a lowgrade talcum in southwest of Henan province based on the ore properties.The test considered the grinding fineness,the collector dosage,the frother dosage,the depressor dosage and the inhibitor species in flotation.Using a process of two stage rougher flotation and one stage cleaning flotation in closed circuit test,the grade of the talc concentrate was 81.20%,with whiteness of 81% and a recovery of 74.24%.The middling were mixed and returned to the circuit.更多还原
