Studied the dependence of the partial pressure of ammonia over the joint water solution of ammonia and ammonium chloride used for the extraction of copper and zinc from the anthropogenic wastes. Developed the calculation method of the values of the partial pressure of ammonia over ammonia water and joint water solution of ammonia and ammonium chloride at concentrations of ammonia and ammonium chloride up to 15% of mass in the solution. Defined numerical values of the coefficients Sechenov for the studied ammonium-ammonia solutions. Installed the salting-out effect of ammonia by ammonium chloride at the concentrations of ammonium chloride up to 3,3 mol/1000 g H2O. Installed that the coefficient Sechenov decreases with the increasing of the concentration of ammonium chloride in the solution.
