Qualitative assessment of the obtained samples of the sand reclaim and of the post-reclamation waste was done, and possibilities of the reuse of the reclaim to replace fresh sand in the manufacture of moulding and core mixtures for aluminium castings were discussed. Guidelines were developed for the sand reclamation process from the waste moulding and core mixtures used in the production of aluminium alloy castings by small foundries.
