Ore composition of limestone

The mineral composition of limestone is mainly calcite, accompanied by dolomite, magnesite and other carbonate minerals, and some other stone cutting machine for granite impurities are mixed. Among them, magnesium appears in limestone and magnesite, silica is free quartz, chalcedony and opal are distributed in the rock, and quarry equipment alumina is combined with silica to synthesize aluminum silicate (clay, feldspar, mica);

Iron compounds exist as carbonates (magnesite), pyrites (pyrite), free oxides (magnetite, hematite), and edge cutting machine hydroxides (hydrous goethite); Chlorite, individual types of limestone also contain coal, asphalt and other organic matter and gypsum, anhydrite and other sulfates, as well as phosphorus and calcium bridge cutter compounds, alkali metal compounds and strontium, barium, manganese, titanium, fluorine and granite slab cutter other compounds, but the content is very low.
