Predominantly chloride sodium and calcium brines with mineralization up to 600 g/dm3 are widespread within the lower level of the Angara-Lena artesian basin. They have high concentrations of useful components: Li, Rb, Sr, B, Br, I, etc. After the extraction of useful components, their further injection in deep-lying aquifers is the most environment friendly and economically viable. It is necessary to carefully plan the selection of a suitable object for disposal the residuals in order to avoid dilution of the concentrations of useful components. The physical and chemical modeling of the interaction in the "water-rock" system and laboratory experiments will be of decisive importance.
