Previous relativistic theories of thermodynamics of fluid mixtures can be extended to include more independent variables. Here the particular case is considered of a 3-constituent mixture consisting of a non-conducting fluid and two charged fluids; extension to the general case is straightforward. A set of field equations is found for the determination of the fields, following the methods of extended thermodynamics. These equations are restricted by the entropy principle and by material objectivity, obtaining in this way a closed hyperbolic system of field equations. As a byproduct of these principles, interesting stringent inequalities are obtained for the relaxation times arising from the production terms.
