What is Dolomite? Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2.Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.. Dolomite and limestone are very similar rocks.
Most dolomite, however, is formed when magnesium-rich waters seep through calcium carbonate rocks, and the magnesium ions replace some of the calcium (up to half). This process takes millions of years to complete, so some dolomite may have only incomplete replacement, and thus be higher in calcium than pure dolomite.
How long does dolomite lime take to work? The amount of time it takes to raise soil's pH level depends on the substance used and the starting pH level, but the process usually takes one to two years. Click to see full answer.
"Dolomite" is a word that is used by geologists in two different ways: 1) as the name of the mineral dolomite; and, 2) as the name of a rock known as dolomite, dolostone, or dolomite rock. This page is about the mineral dolomite. If you are looking for an article about the rock, please go here.
The first process takes place at dolomite mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore. In the iron and steel plant, in some of the places, raw dolomite is further processed. Example is sinter plant where the raw dolomite is crushed in hammer mills to – 3 mm size ...
Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. Learn more about the structure, properties, and uses of dolomite in …

Dolomitization is a geological process by which the carbonate mineral dolomite is formed when magnesium ions replace calcium ions in another carbonate mineral, calcite.It is common for this mineral alteration into dolomite to take place due to evaporation of water in the sabkha area. Dolomitization involves substantial amount of recrystallization. This process is described by the ...
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age).
Dolomite is a complex mineral. It is relatively a soft mineral which can be easily crushed to a soft powder. The mineral is an anhydrous carbonate mineral consisting of a double carbonate of calcium (Ca) and magnesium (Mg). It is chemically represented by CaMg (CO3)2 or CaCO3.MgCO3.
This process of dolomitization is based on the fact that dolomite easily takes place from a mixture of marine and meteoric freshwater than from the sea or freshwater. Dolomitization in the mixed zone of marine and freshwater (brackish) will particularly be intense …
could be used for LB furnace, converter, and ladle, as long as it is possible to meet the customer's requirements. For example, when manufacturing stainless steel, most customers want lime with an extremely low residual C content, while other customers need a somewhat higher content. A general requirement throughout the process chain
The sedimentary process that forms dolomite seems to be somewhat rare. Dolomitic rock is relatively rare in more modern or recent geological formations, or in layers of rock less than 65 million ...

The process of recent primary dolomite formation is restricted to extreme ecosystems such as bacterial mats in highly saline lakes and lagoons. "As these systems are very limited in space, there ...
