Abstract (en)
[origin: WO2013026579A1] In order to regenerate the sand regained from sand molds and/or sand cores which are produced from the sand and soluble glass as a binding agent and used in metal casting, the sand regained from sand molds and/or sand cores is subjected to a mechanical regeneration stage and a thermal regeneration stage, and a hardening agent for soluble glass is added during or after the mechanical regeneration stage.
