Abstract
There were investigated two variants of NaCl isolation from the solutions of human exometabolite mineralization and plant wastes, based on the fractional crystallization of salts via evaporation and the low solubility of NaCl in concentrated HCl, respectively. It has been established that owing to preferential dissolution of the impurities in the concentrated HCl, from the mineralized solutions one could recover 99 % of NaCl contained therein, whose purity of which is not worse with respect to the standard food grade salt. The methods for proposed processing the mineralized solutions allow one to involve NaCl and H2O into the mass exchange within closed environments.
