Dolomite is an anhydrous carbonate mineral composed of nominally equal parts calcium and magnesium, with the formula CaMg(CO 3) 2.Its chemical formula can be more clearly written as CaCO 3.MgCO 3.Because of the presence of two various cations, which form regular layers inside dolomite structure, dolomite crystal symmetry …
Dolomite Description Physical characteristics Dolomite is a common mineral. It is also known as CaMg(CO3)2 and is a type of compact limestone consisting of a calcium magnesium carbonate. In combination with calcite and aragonite, dolomite makes up approximately 2% of the earth's crust.
Uses of Dolomite. Dolomite has a myriad of practical applications. In agriculture, dolomite and dolomitic limestone are used as pH buffers in soil management and in potting mixes. In construction, dolostone may be used instead of limestone as the aggregate in cement mixes. Dolomite also serves as a vital component in the production of glass and ...
The most common uses of limestone, dolomite, and coquina are as crushed stone or aggregate products. The crushed stone is the basic raw material that can be processed further, if necessary, for roadbase, cement manufacture, fertilizer and soil conditioners, rip rap and other uses. Market conditions or customer specification, of course, will ...
Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3) in the form of mineral calcite or aragonite.It is one of the most common and widely distributed rocks on Earth, with a wide range of uses in various industries and natural settings. Limestone forms through the accumulation and compaction of marine organisms, primarily the …
