This work is devoted to the investigation of the mixture of magnetic and nonmagnetic particles in the hydrodynamic limit. Analysis of the structure of hydrodynamic matrix allows to consider the hydrodynamics of a multicomponent mixture. It was shown that among the collective modes there exist two sound and $m$ dissipative modes, where $m$ is determined by the number of additive integrals of motion. The analytical expressions for the time correlation functions constructed on the basis of density operators of conserved quantities, were derived. On this basis expressions for the dynamical structure factors were derived for the case of binary mixture of magnetic and nonmagnetic particles in the paramagnetic state.
