An analytical solution and method of calculation is presented for a cascade of N perfectly mixed batch extractors operating counter‐currently, for spherical solid particles, with parameters which may vary for each extractor. The results for the case of constant and equal parameters along the complete cascade are presented in dimensionless plots; N varies from 1 through 10. The practical interest of these diagrams lies in their use in design and/or in foreseeing the behavior of a cascade when its parameters undergo variations. A sample calculation is included.
