quarrying and proccessing of ornamental stone

  • DRAFT REPORT STATE-OF-THE-ART: ORNAMENTAL STONE

    The quarrying of ornamental stone is generally not covered by mining laws in Europe, and there are no European directive on quarrying, mineral right claims and exploration. The practises and legal framework on mining vary significantly throughout Europe, including the way ornamental stone is treated compared to other mineral commodities.Quarrying of Stones: Its Methods, Selection of Site,The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones. It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging below the ground, sometimes at considerable depth.

  • A review on the utilisation of quarry and ornamental stone

    During extraction, around 30% of the stone goes to scrap because of small size and/or irregular shape [19,20]. Moreover, large quantities of stone fines (named quarry dust) are generated, whichQuarrying Process And Quarry Products,Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into the sizes required for immediate use, or for further processing, such as coating with bitumen to make bituminous macadam (bitmac) or asphalt.

    Blasting produces small (8 to 10 metric tons) irregular pieces; over 50 percent of which is wasted in processing. At the processing plant, lack of adequate equipment and processing techniques applied to stone that was previously damaged leads to more inefficiency. Efficient dimension stone production, however, requires special quarrying methods.Decision criteria for the exploration of ornamental-stone,During the process of geological ornamental-stone deposits exploration, the unique and decisive criteria that should be considered are its dimensions, homogeneity, and fracturing state.
