FIELD: mining.
SUBSTANCE: invention refers to benefication of mineral deposits and can be used for separation of xenospheres and for obtaining concentrates of less-common and rare-earth elements out of ash-slag of thermal power stations. Flow line for separation of rich components out of ash-slag wastes includes in-series connected silo, devices for magnetic separation in strong and weak fields, electrostatic separator, leaching vat. In addition, the line is equipped with in-series connected flotation machines installed after the receiving hopper and intended for separation of xenospheres, and with classifiers for separation of material into size grades, for its further processing in various flows. Also the line is equipped with additional magnetic and electrostatic separators, leaching vats, filters and driers, which are installed in series after the classifier.
EFFECT: increasing the separation level of metals and content of rich components in the concentrate.
