ABSTRACT:
The invention relates to a method of reclaiming contaminated industrial sand including the steps of subjecting the sand to the influence of heat in a fluidizing bed, forcing sand fed to said bed to follow a flow path including a plurality of generally heightwise directed path portions including at least one generally upwardly directed path portion and at least one generally downwardly directed path portion. In an example of the invention, the heat is applied to the sand in a first group of path portions and the sand is cooled in a second group of path portions.
