For 16 metals the minimum theoretically possible specific expenses of energy for obtaining of their powders by electrophysical methods are calculated. For Al and Fe the minimum theoretically possible specific expenses of energy for their electrochemical dissolution are calculated. Power processes are observed and factual specific expenses of energy are defined for obtaining of fine-dispersed powders of Al by plasma-erosive dispersion of its granules in water and for obtaining of its ions by electrochemical dissolution of Al and Fe electrodes in water. The comparative analysis of power efficiency of electrophysical and electrochemical methods of obtaining of powders and ions of metals are given. Ways of its raise are analyzed.
Key words: electrospark and plasma-erosive dispersion of metals, fine-dispersive particles, electrochemical dissolution, specific expenses of energy, power efficiency.
