Limestone Mining. LIMESTONE MINING. Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make u...

Yes, limestone reacts with acids. Permalink Submitted by chris on Sun, 05/11/2017 - 10:22. Limestone is calcium carbonate (CaCO 3 ). Carbonates react with acids according to the equation: CO 32- + 2H + -> H 2 O + CO 2. However, the rate of the reaction will be determined by a number of factors. First, the strength of the acid.Most limestones are classified by Folk allochemical Rocks if they contain over l0% allochems (transported carbonate grains).
