The investigation results of the thermal reclamation of spent core sands made in the hot-box technology are presented in the paper. Energy-consumption of the process was tested by recording the media consumption during the thermal treatment of the determined intensity. Gas demands in dependence of the reclamation process temperatures were compared. During the reclamation process the reclaimed material samples were taken to test ignition losses in order to determine the efficiency of the realised procedures. The influence of the reclamation temperature on the quality of the obtained reclaimed material was checked. The effects of the realised reclamation procedures of the same moulding sand at various temperatures were also assessed on the grounds of strength of moulding sands prepared on the bases of the obtained reclaims. It was found that the process energy-consumption can depend on the expected core sand parameters. The attention was drawn to the fact, that bearing of costs for the thermal reclamation - very often - does not correspond directly with the obtained effects. The thermal reclamation performed very intensively, which corresponds with the costs increase, is not always needed for obtaining the core sand of parameters comparable with the sand made of fresh components.
