Centrifugal contactors are efficient extraction equipments and have been successfully used in some industrial fields. But many of the extraction systems contain H2SO4 or HCl, therefore, centrifugal contactors that their main material is the stainless steel or titanium can be corroded by these acids not to be used in these systems. In order to solve the problem, a centrifugal contactor with 70 mm of the rotor diameter that the main material is the glass fiber reinforced plastic (GFRP) has been developed at Institute of Nuclear and New Energy Technology, Tsinghua University, China (INET). The mechanical performance of GFRP satisfies the operating requirements of the centrifugal contactor. The maximum total flow of the single stage contactor can reach 200 L/h at suitable operating conditions for H2O-kerosene system. The extraction stage efficiency is greater than 95% at suitable operating conditions for both extracting Co2+ with 35% N 235 (tertiary amine)-20% iso-octyl alcohol-45% kerosene from CoCl2 solution and stripping Co2+ with 0.1 mol/L HCl solution from the organic phase (35% N 235 -20% iso-octyl alcohol-45% kerosene) containing Co2+ .
