ABSTRACT A theoretical model of the migration process of high‐alkalinity red mud particles in porous media was derived from granular thermodynamics, complying with the complementary motion process of two‐phase flows (i.e., hydroxide ions and red mud powder). From the perspective of energy dissipatio...
