Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).
Commodity: Limestone, a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calcium-magnesium carbonate (formula CaMg(CO3)2).lso, the calcination (that is, the burning) of this same 100 tons of limestone would produce 45.10 tons of carbon dioxide gas (formula CO2). Limestone, however, is very rarely pure calcite, pure dolomite, or a pure mixture of the two.
