involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of large-scale mining projects involving these metal ores are the subject of this Guidebook. The Guidebook does not discuss the mining of ores that are extracted using strip mining methods,

This paper aims to improve the marble industry production chain by proposing new technological approaches using the Radio Frequency Identification (RFID) systems. The dynamic capabilities of the RFID read-write tags allow the storage of physical characteristics of stone blocks, according to electrical, ultrasound and three-dimensional image characterization tests.

Classification of marble image according to usage purpose and quality is an important procedure for export. Discrimination between marble varieties is a difficult task during selection, since it requires trainings and experience. Therefore, the development of automatic prediction model based on image processing is a potential application area to support experts across the world.

2.3. SOX extraction. The SOX process is a traditional method that is widely applied to extract the oil from organic matrix, which is used when the desired compound has limited solubility in a solvent while the impurities are insoluble in this solvent .Bajer et al extracted capsaicinoids from many chili samples using the SOX method with methanol as solvent and an extraction time of 2 hours.

The marble extraction of the Piastreta quarry is executed in tunnel within a D 1 geological structure known as the "Monte Tambura" antiform. The quarry is located in the inverted limb of the antiform, an E-NE vergent fold located in the central area of the Apuan Alps, with an amplitude of about 15 km and a general N-S strike ( Figure 1 ).

In marble quarries, stones are cut as blocks through different methods. During the cutting process, 20-30% of a marble block becomes waste marble powder. Marble powder is a waste material generated in considerable amounts in the world. Marble waste leads to a serious environmental problem as well.
