In this part of the article the essence, mechanism, conditions and methods for intensification of flotation processes necessary for increase in technological and economic indices of dressing of ores of nonferrous metals are considered. It is shown that optimal conditions for various methods of intensification of recovered minerals flotation are the methods for securing of flotation theory requirements to the composition of the collector sorption layer on their surface. Optimization of the collector sorption layer on the surface of minerals to be recovered is achieved by cleaning of their surface and its activation with heavy metals salts, by activation of oxidation processes of ionogenic heteropolar collectors, by use of additional nonionogenic apolar collectors and mixtures of ionogenic and nonionogenic heteropolar collectors. Necessary relaxation parameters of the bubbles surface can be provided with formation on it of definite overmolecular structures of organic hydrophobic substances. Conditions necessary for optimization of intensification processes can be determined as a result of physical-chemical modeling of corresponding flotation systems.
