The continuous extraction process of NBPT was studied through adopting the one-stage of D20 annular centrifugal extractor with water as the extractant. The experiment was studied at a rotor speed varied from 1500 r/min to 5000 r/min,a phase ratio range of 1~7 to 1,a totle flow from 50 mL/min to 110 mL/min and annulus of 5.5 mm. The extraction efficiency of mineral salt was achieved to 97 %.
