Different microorganisms studied. As biosorbents emerge different microorganisms: bacteria, micromycetes, fungi, yeasts (baker's, beer and forage), active silts and microalga. As native sorbents studied active carbon and chitines, chitisan. Flotation biomass from the liquid, so named biosorbtive flotation we consider as promising. Scientific and practical urgency of problem consists in revealing an intercoupling between the sorption of non-ferrous metals by the biomass and its floatability, determination of optimum parameters for regulation flotation biomass, loaded by metals. An ability to sorption metals from solutions possess all microorganisms - bonding of metals is realized to the account of different mechanisms (ion exchange, complexing, reducing, formation low soluble compounds). Adsorptive capacity of microorganisms end efficiency of metals recovery determined. For instance, maximum Cu and Ag recoveries were about 100% from100 ml solutions 1 g/l/ on 10 g biomass. Floatability of sorbents greatly depends on sorption metals on their surface: mostly metals activated flotation, most of synthetic sorbents displayed pure floatability in ether cases. Biosorbents floated with greater ability. The concentration of metals (or removal toxic inorganic ions) by microorganisms with following flotation can become industrial process both for a cleaning sewages, and for a recovery of metals. There is much reason for making broad study and further development of that field of research with control of metal contents in solution by Ecotest apparatus with ion- selective electrodes on Cu, Ag, Ni, Co etc.; control of both - solution and solids (sorbents, minerals) with Spectroscan G roentgen-fluorescence spectrometer.
