SEPARATION OF MATERIALS FROM PROCESSED ELECTROCHEMICAL CELLS AND BATTERIES Russian patent published in 2015 - IPC B09B3/00 H01M10/54 B03D1/02 B03B9/06 

FIELD: process engineering.

SUBSTANCE: invention relates to processing of electrochemical cells and storage batteries. Proposed method comprises mincing of storage battery, removal of case materials, suspending of produced battery suspension in water in foam flotation tank. Foam flotation agent is added to said suspension to bubble said tank by air to produce foam. This allows hydrophobic materials to be trapped by air bubbles and trapped materials to afloat with said trapped materials. Compounds Pb (IV) are separated from compounds Pb (II) in battery suspension in foam flotation tank. Method of separation of materials in wastes of lead-acid batteries comprises extraction of pasted from used battery, suspending of extracted paste in water, addition of foam flotation agent to said suspension including paste and water, bubbling of said tank by gas to get the foam, separation of (PbO₂) from other lead-bearing compounds of suspension is said tank.

EFFECT: higher efficiency of separation.
