Dynamic properties of a binary mixture of magnetic and nonmagnetic particles is considered with the help of the method of nonequilibrium statistical operator. The generalized hydrodynamic equations are derived and analyzed. On this basis hydrodynamic collective modes spectrum was calculated. The expressions for sound velocity and damping coefficients of collective hydrodynamic modes are found. We propose the consistent scheme for calculation of time correlation functions in the hydrodynamic limit and discuss the expressions found for them in paramagnetic case.
