Popis:	The process of isolation of ferrous and nonferrous metals from diluted solutions in the form of simple hydrated cations and anions of complexes, as well as the dispersed phase of hydroxides and poorly soluble sublates, respectively, in the modes of “foam fractionation” and ion (“foam”) flotation, is studied. The flotation rate constant and the concentration coefficient of metals upon ion flotation are ascertained to be several times higher than those upon foam fractionation. A technological scheme for finish purification of industrial wastewater by flotation is proposed. The prevented environmental and economic damage from the contamination of the environment by wastewater is calculated.
