milling process of dolomite to calcium carbonate

A completed sedimentation process results in the formation of limestone. If the sedimentation process takes place in water containing magnesium, dolomitization may occur. Part of the calcium ions in the crystal lattice are replaced by magnesium ions, leading to the formation of dolomite (CaMg(CO 3) 2).

(PDF) Magnesium Production from Calcined Dolomite via the ...

The invention provides a process for producing magnesium hydroxide and calcium carbonate by the dolomite conversion method. The process comprises the following steps: calcining dolomite, carrying out a digestion reaction on dolomite and water and refining so as to obtain a refined slurry of calcium hydrate and magnesium hydroxide; reacting the slurry with an ammonium chloride solution to ...

Lime (material)

Dolomite is also slightly harder, denser and never forms scalenohedrons (calcite's most typical habit). Dolomite differs from calcite, CaCO3, in the addition of magnesium ions to make the formula, CaMg(CO3)2. The magnesium ions are not the same size as calcium and the two ions seem incompatible in the same layer.

Calcium Carbonate Wikipedia. Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite most notably as limestone which is a type of sedimentary rock consisting mainly of calcite and is the main component of pearls and the shells of marine organisms snails and eggs.

Magnesium Production Residues

Nov 01, 2015· The aim of this study was to analyze the catalytic performance of natural dolomitic rock as an environmentally friendly catalyst in the reaction of Jatropha Curcas oil with methanol under microwave-assisted transesterification. The dolomite was utilized as a source of calcium oxide (CaO) and magnesium oxide (MgO).

production process of dolomite

By use of a recarbonation process, it is possible to separate magnesium carbonate and calcium carbonate from dolomites/dolomitic limestones. Magnesium carbonate can be used for manufacturing basic refractories and magnesium chemicals; the portion rich in calcium carbonate can be used for cement manufacture if the MgO content is below 3%.
