We review the current status of the problem of metal mixing in the intergalactic and interstellar media. We give simple arguments for inefficiency of mixing metals because of a saturation of hydrodynamic (Rayleigh-Taylor and Kelvin-Helmholz) instabilities. We describe mixing in two typical processes: stripping of a galactic gaseous halo and cloud-cloud collision. We show that statistical features of metal distribution observed in the intergalactic medium is close to those obtained in our numerical simulations.
