For the purpose of optimizing the counter current extraction process some new equations have been derived for calculating the optimized extraction factors to search the minmum total volume of mixer settler extractor or scrubbing section at the same production capacity and product quality. With new equation the error rate of the expansion approximation equation of logarithm is small, the calculated optimized extraction factors are more precise. The new equations derived are able to calculate precisely the optimization extraction factors.
