Dolomitization process and its implications for porosity ...

As the dolomite increases from 50 to 75% (stage II-1), the porosity begins to increase slowly with values up to 6%. Where dolomite exceeds 75% (stage III), there is a rapid increase in porosity to value of approximating 12% at 8085% dolomite. As the dolomite contents increase above 85% (stage IV), the porosity decreases progressively.

Dow Process - Magnesium

In the Dow process is magnesium hydroxide is precipitated from sea water by slurrying with calcined dolomite and then converting it to magnesium chloride by reacting it with hydrochloric acid. This product is dried to 1,5 moles of water and introduced directly into the cells.

Dolomite: A sedimentary rock known as dolostone or dolomite rock

The dolomitization process results in a slight volume reduction when limestone is converted into dolomite. This can produce a porosity zone in the strata where dolomitization has occurred. These pore spaces can be traps for subsurface fluids like oil and natural gas.

DOLOMITE (Calcium Magnesium Carbonate)

These rocks are called appropriately enough dolomite or dolomitic limestone. Disputes have arisen as to how these dolomite beds formed and the debate has been called the "Dolomite Problem". Dolomite at present time, does not form on the surface of the earth; yet massive layers of dolomite can be found in ancient rocks.

dolomite | Formation, Structure, Properties, Uses, & Facts ...

Dolomite effervesces with dilute hydrochloric acid, but slowly rather than vigorously as calcite does; in general, it appears to smolder slowly, and in some cases it does so only after the rock has been powdered or the acid warmed, or both. This difference in the character of the effervescence serves as the test usually used to distinguish dolomite from calcite in the field.

Extractive Metallurgy: Magnesium Extraction By Dow Process

The magnesium concentration in dolomite by weight is 28.8%. The process developed at Dow (see Fig. 2) is unique, due to the fact that the material fed into the electrolysis cells still contains a significant amount of water about 27%.

Agricultural Lime vs. Dolomite Lime - Braen Stone

Aglime and dolomite both become useful when soil becomes too acidic. This typically occurs after exposure to acid rain, after frequent use of fertilizers and other chemicals or even after the soil has simply become deprived of important nutrients from years of planting and harvesting crops.

Dolomite and dolomitization model - a short review

divided into two groups: primary dolomite and secondary dolomite.2 Primary dolomite precipitate directly from aqueous solution, mostly at or near room temperature (20-35oC), with no CaCO 3 dissolution involved.3 However, dolomite can also form as a secondary phase replacing the precursor mineral calcite (dolomitization process).

The "Acid Test" for Carbonate Minerals and Carbonate Rocks

Dolostone: Dolostone is a sedimentary rock composed primarily of the mineral dolomite, which has a chemical composition of CaMg(CO 3) 2. Dolomite will effervesce weakly with cold hydrochloric acid, producing a few bubbles. The reaction is more noticeable when the acid is warm and/or the stone is powdered. The specimen in the photo is about 10 ...

Dolomitization | mineralogy | Britannica

Dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg (CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume. Dolomitization involves recrystallization on a large scale.
