The processing of granite dimension stones essentially involves the following major operations: quarry opening; blasting; cutting; polishing and ornamenting. Quarrying for dimension stone requires a specialized method of extraction. Normal quarrying methods use large quantities of explosives to move huge volumes for breaking down into aggregate.

Open-pit quarrying is a cost-effective method for extracting large building stone blocks, particularly for stones like granite and limestone, using heavy machinery and explosives. Wire sawing offers precision and reduced environmental impact, making it ideal for high-value stones such as marble and granite while supporting sustainable practices.
Critical raw materials (CRMs) supply is a challenge that EU countries have to face, with many thinking about domestic procurement from natural ore deposits and anthropogenic deposits (landfills and extractive waste facilities). The present research focuses on the possibilities linked to the supply of CRMs and the potential for exploiting rare earth elements …

This paper presents the results of a new method that has been tested to recover metallic cobalt lost by diamond beads from rock cuttings. When dimension stones are cut using diamond wire saws, the beads become worn and, before the end of their cycle life, lose a certain amount of material; this material is prevalently made up of sintered metal and diamonds. The …
