Limestone is an important construction material. But limestone is mostly used for cement making. White and pure caco3 can be used for decorate the pillar or crafts while the caco3 with impurities- the so-called marble can be used for flooring or wall tile.Limestone, with Mohs’ hardness 3, consist mainly caco3.
, these rock can be classified into several catergories into hard, medium hard and soft rocks. Other types of rock and stones include marble, shell, talc, barite and slate. The main rock types processed by the crushed stone industry include limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Various rock crusher plants are available for crushing all these rock and stones.There are numerous rock types in the natural wold. Due to different properties, such as hardness and density etc.

These monazites contain high and variable amounts of SrO ranging from 0.94 wt % (Figure 6c–f; Supplementary Materials Table S2) [15,23].1–1.The first substitution scheme represents a solid solution series between monazite (CePO4), cheralite [CaTh(PO4)2], and SrTh(PO4)2 , commonly known as the cheralite substitution [44,45]. ThO2 content variation has also been identified within the large crystals, for instance, those from the Abyan deposit were observed to decrease from2 wt % in the center to0. Again, both huttonite and cheralite solid substitution in monazite have been identified for the Sokli complex and the Lesnaya Varaka complex, with ThO2 content as high as 34. The high Th content is most common in high-temperature monazite .5 wt % ThO2) though the huttonite mechanism may play the dominant role given that better correlation between ThO2 and SiO2 has been identified (Figure 6a,b) . Accommodation of Th in monazite may involve a coupled substitution with Si as listed as the second scheme, which is known as the huttonite substitution [20,44,45].92 to 4 wt %, which display co-substitution with Th (Figure 6e,f). The cheralite substitution mechanism may indicate selective removal of Ca and Sr from apatite in the presence of a REE-rich hydrothermal solution as well as the immobility of P, which is indicated by the petrographic texture of monazite replacing apatite (Figure 3). Both substitutions contribute to the accommodation of Th in Naantali monazite (with a range of 1.2 wt % and CaO contents ranging from 0.5 wt % at the rim and along the fractures .92 to 4.
