Calcined dolomite, calcium magnesium oxide, (CaMg(O) 2) How it's produced: By heating the mineral dolomite (CaMg(CO 3) 2). Uses: In steelmaking, both quicklime and calcined dolomite are used as a flux and slag conditioner and to prevent the steel from oxidising. This process also collects impurities that are damaging to the steel.
Oct 01, 2017· Tubular magnesium oxide (MgO) nanocrystals were fabricated via combining ammonium sulfate leaching and precipitation method with calcined dolomite (CaCO 3 ·MgO) as magnesium source. The relationship between (NH 4) 2 SO 4 /MgO molar ratio, volume of distilled ammonia and dosage of calcined dolomite and the leaching rate of magnesium were investigated, and the highest …
18 dolomite, as a novel alkali activator, to 5% sodium sulfate attack and 5% magnesium 19 sulfate attack. Two calcined dolomites, D800 and D1000, were prepared in the 20 laboratory at 800 °C and 1000 °C respectively. The results demonstrated the good 21 potential of using calcined dolomite activated slag in resisting sulfate attack. 22 ...
Calcined dolomite - CALCINOR. Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings.

In the thermal reduction process, magnesium oxide, as a component of calcined dolomite, reacts with a metal such as silicon to produce magnesium. The silicon is usually alloyed with iron. There are two principle methods: (1) carbothermic, and (2) silicothermic.
The addition of calcined dolomite has an apparent effect on increasing the thermal conductivity of hardened paste specimen at 28 days by about 7.03, 12.79, 22.41, and 28.77% with the added amount ...
Jan 20, 2021· In 1942, Dow provided more than 84 percent of the total United States output of magnesium. During World War II a plant near Austin used Burnet County Ellenburger dolomite rock for large-scale production of magnesium. Between 1945 and 1947 demand declined, but Dow continued to stockpile ingots, and in 1948 Texas ranked first in quantity… Read more
