One way to alleviate the environmental problem associated with the disposal of granite processing waste is to utilize this material as aggregate in concrete manufacturing or as raw material for producing concentrates to be used in the ceramics industry. Based on the results of material characterization and amenability tests conducted on Sardinian granite waste, the paper demonstrates the potential utilization of this type of material as a concrete ingredient and in cement blends. Likewise, the application of basic mineral processing techniques, such as magnetic separation, integrated where necessary with flotation, showed that the beneficiated products of the same granite waste as well as of road tunnelling waste should find a ready market in the ceramics industry.

Abstract
One way to alleviate the environmental problem associated with the disposal of granite processing waste is to utilize this material as aggregate in concrete manufacturing or as raw material for producing concentrates to be used in the ceramics industry. Based on the results of material characterization and amenability tests conducted on Sardinian granite waste, the paper demonstrates the potential utilization of this type of material as a concrete ingredient and in cement blends. Likewise, the application of basic mineral processing techniques, such as magnetic separation, integrated where necessary with flotation, showed that the beneficiated products of the same granite waste as well as of road tunnelling waste should find a ready market in the ceramics industry.
