제목 Process intensification and kinetic studies of Mn extraction from LIBs waste leachate by D2EHPA
초록 Manganese (Mn) is one of the crucial metals in lithium battery materials and needs to be recovered. The current study demonstrated the continuous process of Mn liquid-liquid extraction from waste lithium battery leachate. The equilibrium constants for the aqueous and organic-phase reaction complex are investigated and applied to the numerical model. The continuous process model includes extraction by di-(2-ethylhexyl)phosphoric acid (D2EHPA), scrubbing and stripping by H2SO4 steps. The effects of organic/aqueous phase volume ratio (O/A ratio), the concentration of D2EHPA, saponification rate, concentration of H2SO4 and composition of waste leachate with total Mn extraction efficiency were studied. Through the simulation data, the optimal operation condition was determined.

Keywords: Mn extraction, Lithium batteries, kinetic model, continuous process model, saponification
