On the basis of thermodynamically self-consistent integral equations for the pair structure it is shown that dense binary mixtures of hard spheres, of diameters σ1 and σ2, phase separate when the size ratio σ1/σ2 is less than 0.2, and the partial packing fractions of the two species are comparable.
