We present a study of a phase-separation process induced by the presencee of spatially-correlated multiplicative noise. A mean-field approach for conserved-order-parameter systems is developed, and used to obtain the phase diagram of the model. Mean-field results are compared with numerical simulations of the complete model in two dimensions .
Additionally, a comparison between the noise-driven dynamics of conserved and nonconserved systems is made at the level of the mean-field approximation.
