Abstract
A process is disclosed for the regeneration of used foundry sand, whose original molding sand contained as molding material inorganic bonding agents such as bentonite (= "inorganic used sand") and/or organic bonding agents such as phenolic and/or furan resins (= "organic used sand"). The used sand to-be-cleaned is soaked with water and subsequently moved into a heated fluidizing bed in its wet condition.
