As one of leaders of processing dolomite to calcium carbonate industry, SBM always seeks innovation & excellence.
Dolomite is a carbonate (like whiting) in that it loses considerable weight during firing when it disassociates to form MgO, CaO and CO 2, this process being complete by about 900C. In many circumstances where a raw glaze employs both CaO and MgO, dolomite is an economic alternative to sourcing with a mix of calcium carbonate and talc.

In dolomite, carbonate is chemically combined with calcium and the element magnesium (symbol Mg) to form calcium-magnesium carbonate (formula CaMg(CO3)2). In dolomite there is one magnesium atom for every calcium atom. The amounts of calcite and dolomite in theoretically pure limestone range continuously from all calcite and no dolomite to all ...

The Dolomite Mountains, Italy's Alpi Dolomitiche, however, are a special case: the rock in them was originally simple calcium carbonate made from dead corals and seashells on the seafloor. Only later was it transformed into dolomite through the orderly addition of magnesium--and through the action, McKenzie suspects, of sulfate-reducing bacteria.

carbonate from dolomite. This process uses carbon dioxide from the result of calcinations process so it makes this process environment friendly. Separation process between magnesium and calcium from dolomite with carbonation process will be successful if in calcinations process, the calcium carbonate does not change into calcium oxide (CaO) [6].

Calcium carbonate is an exceptional compound. The chemical formula CaCO 3 represents a raw material that exists everywhere in nature – whether dissolved in rivers and oceans, melted as "cold" carbonatite lava and solidified as a mineral, dripstone or as a parent material for whole mountain ranges.. Plants and animals need calcium carbonate to form their skeletons and shells, and even modern ...

Sep 30, 2012· Introduction ()Dolomite, calcium magnesium carbonate, with the chemical formula CaMg(CO3)2 is made up of 60% calcium carbonate (equivalent to 24% calcium) and 40% magnesium carbonate (equivalent to 12% magnesium)Déodat Gratet de Dolomieu, a French geologist, was the first to describe dolomite in 1791. He observed dolomite in a mountain in northern Italy, now named the Dolomite .

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate .

About Calcium Carbonate. Calcium Carbonate (a.k.a. CaCO3) is a non-toxic and odorless inorganic salt, commonly found as a white mineral (calcite) which occurs naturally in chalks, limestones and marbles. These rocks are classified as limestones, a general term used for a rock containing varying proportions of calcite and dolomite.

Dolomite, which is named for the French mineralogist Deodat de Dolomieu, is a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick.They are found all over the world and are quite common in sedimentary rock sequences. These rocks are called appropriately enough dolomite or dolomitic limestone. Disputes have arisen as to how these dolomite .

Dec 03, 2013· Dolomite. Dolomite is also a carbonate mineral but is made of 'calcium magnesium carbonate' instead of pure calcium carbonate material. Therefore, dolomite is called a double carbonate rock, and it doesn't readily dissolve in dilute acidic media. The way dolomite is formed is not quite clear, and it has been found that it forms under high ...
