Abstract: Based on a series of laboratory experiments on a unique installation for upward filtration lifting of solutions of water-soluble salts of nonferrous metals, the regularities of mass transfer and surface deposition at the evaporative barrier have been obtained. It was found that the intensity of evaporation has a linear tendency to decrease with time, which is associated with changes in the porosity of the massif in the aeration zone. Redistribution of vertical zonality of salt deposition concentration in the surface zone of the array is possible by controlling the evaporation intensity. Regularities of salt concentration distribution in different levels of the massif have been established, which forms the basis of the mathematical model of the fluid-mass transfer process.
