Abstract

A method of thermally reclaiming a base material from a mixture of the material and a combustible substance, wherein said substance is incinerated in a fluidised bed, comprises feeding said mixture directly into a lower part of the fluidised bed. Also described is thermal reclamation apparatus for thermally reclaiming a base material from a mixture of that material and a combustible substance, the apparatus comprising a fluidised bed, and means for feeding said mixture directly into a lower part of the fluidised bed. The method and apparatus are particularly suitable for the thermal reclamation of foundry sand or other base materials used in foundry processes.
