Dolomite is a calcium element or magnesium element carbonate mineral. CaMg (CO3)2 is the formula unit composition. The trigonal crystal system of dolomite has a rhombohedral habit. Unlike magnesian calcites, calcium and magnesium are divided into complete separate planes in ideal dolomite.
Dolomitic Limestone was originally known as "Magnesium Limestone," as it contains high levels of magnesium instead of just calcium. So just about anyone who can use magnesium should be interested in it. These days, it is now mostly referred to as "Dolomite," "Dolostone," "Dolomite Rock," or "Dolomitic Limestone."

Dolomite is an anhydrous carbonate mineral made up primarily of calcium magnesium carbonate (CaMg (CO3)2). A sedimentary carbonate rock consisting primarily of the mineral dolomite is also known as a dolostone rock or dolostone rock type. The word "dolostone" is often used to refer to the dolomitic rock type. Dolomite is a type of …

In 1913, production of magnesia (magnesium oxide) by precipitation using dolomite began in Pennsylvania. Deposits in Stevens County, WA, were recognized as magnesite in 1916, and mining started the next year. Mining of brucite began in 1929 from a depo sit in Nye County, NV, and in 1937, magnesite mining started in a nearby deposit.
