Pyrochemical extraction analysis of an immiscible molten LiCl-KCl/Cd system

A pyrochemical extraction is one of the promising unit operations used in the pyrometallurgical process for the separation of actinides from fission products mixture with the aid of extracting the solvent and oxidant. A rigorous computational model for the simulation of multi-stage counter-current oxidative extraction was developed by using model equations, composed of a material balance and distribution relationships between the molten-salt and metal phase stream. The solutions were determined using the equation tearing algorithm. It was observed that this modeling approach allows us to provide simulations for the effect of the operating variables on the recovery of group actinides. (author)
