Dolomite – Its Processing and Application in Iron and ...

28/06/2017  In the production of direct reduced iron (DRI) by the rotary kiln process, dolomite is used as a desulphurizing agent. Raw dolomite is used in the size range of 4 mm to 8 mm. The second major use of dolomite is in steelmaking. In steelmaking dolomite is used both as a fluxing material and also as a refractory material. For use in steelmaking, the SiO2 (because of its acidic nature) content in ...

Dolomite - Uses Britannica

Dolomite - Dolomite - Uses: Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination has become a widely heeded ...

Dolomite (mineral) - Wikipedia

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smeltingof iron and steel. Large quantities of processed dolo

Except for models invoking formation of dolomite by direct precipitation, a process thought by most geologists to apply to only a small percentage of all dolostones, each model is based on the assumption that the dolomite of dolostones has been formed by conversion of CaCO 3 sediment or sedimentary rocks to dolostone. Thus, the models have been formulated to account for this conversion, which ...

Dolomitization - an overview ScienceDirect Topics

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 when the mixture contains between 5% and 50% seawater. The water mixed with a ratio of 5–50% seawater and 95–50% of meteoric ...

Manufacturing Process Dead burnt refractory dolomite is produced in rotary kilns. Generally high-grade dolomite, containing combined impurities less than 3%, is selected for dead burning. As it is difficult to densify high purity dolomite in a rotary kiln, it is customary to use some mineralizers to facilitate dead burning. Iron oxide is a common additive. The manufacturing process varies with ...

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.
