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 ...

Hydrothermal Dissolution of Deeply Buried .
The burial dissolution of carbonate rocks has long been an interesting topic of reservoir geologists. Integrated with geological studies and reactive transport modeling, this study investigated the Cambrian dolomites that were buried at depths up to 8408 m and still preserved a large amount of unfilled dissolution vugs from the borehole TS1 in the northern Tarim Basin.

01-06-2015· The calcined dolomite used as a catalyst showed promising results for biodiesel production by transesterification reaction of canola and sunflower oils refined with methanol. The thermal treatment of dolomite (850 °C/3 h) produces small particles of mixture oxides (CaO and MgO) which are responsible for the observed catalytic activity.
