FIELD: methods for production of binding material based on aluminum hydrooxochlorides for manufacture of ceramic molds in foundry. SUBSTANCE: wastes of melting of aluminum alloys are washed to remove water-soluble metal chlorides treated with hydrochloric acid in compliance with stoichiometry of production of basic aluminum chloride Al2(OH)5Cl.. EFFECT: higher efficiency.
