FIELD: chemistry.
SUBSTANCE: installation for bacterial leaching of metals from technogenic wastes includes apparatus for accumulation of microorganism mass in liquid medium with technogenic wastes, apparatus for leaching metals from technogenic wastes, unit for separation of metals from liquid medium with technogenic wastes in form of apparatus for ionic floatation and unit for regeneration of leaching solutions in form of reservoir with pneumatic system of aeration. Apparatus for accumulation of microorganism biomass is equipped with turbine mixer and external cooling circuit. As apparatus for metal leaching, used is multi-chambered floatation apparatus with devices of flow of liquid medium with technogenic wastes from chamber to chamber, made with possibility of changing conditions of aeration and intensity of mixing.
EFFECT: increased degree of metal leaching from technogenic wastes.
