This operation is devoted to research of processes of a fluid mass transfer in an array of breeds and to formation of concentration zones in it by creation of a barrier of evaporation. evaporation parameters from different factors and parameters of vertical zonality of sedimentation of non-ferrous metals in a zone of aeration of an array are studied. For these purposes the experimental installation for study of vertical zonality of sedimentation of secondary minerals in a near-surface zone of aeration of an array is developed and made. Maintenance of constant level of solution in an array was carried out by means of a tank of Marriott adapted for experimental conditions. As a fluid solutions of different concentration of cobalt (II) nitrate 6-water and nickel (II) of the nitrate 6-water are used. Nature of sedimentation of water-soluble Ni and Co nitrates depending on conditions of capillary rise of solution in an aeration zone when passing a transpiration barrier is set. Speakers of speed of evaporation has an exponential appearance and depends generally on humidity of air.
