Recent Molecular Dynamics results for the charge fluctuation spectra of binary ionic mixtures immersed in a neutralizing background are analysed on the basis of the coupled generalized Langevin equations for the partial densities. Good agreement with the simulation data is achieved, except at low frequencies. The spectrum of the k-dependent interdiffusion current correlation function is shown to exhibit well separated low and high frequency peaks linked to mutual diffusion of the two species and to plasma oscillations respectively.
