Dolomite is a mineral and a rock-forming mineral that is composed of calcium magnesium carbonate (CaMg(CO3)2). It is named after the French mineralogist Déodat Gratet de Dolomieu, who first described its properties in the late 18th century. Dolomite is often found in sedimentary rock formations and can occur in a variety of …
The distribution of Dolomite mine sites in Indonesia can be found in Gresik, Lamongan, Rembang, Padang, Medan, Aceh, and Sulawesi. However, the best quality of Dolomite is in Gresik, East Java with levels of MgO that can reach up to 25%. Therefore, by an exclusive partnership with the best Dolomite mine in the Gresik area the quality of ...

Dolomite, CaMg(CO 3) 2, is an abundant carbonate mineral in ancient rock formations, but it is extremely scarce in modern sedimentary environments.This intriguing observation has been repeatedly referred to as the "dolomite problem" in the geological literature. Many geoscientists over time have almost obsessively searched for a solution …
Five categories of raw materials are distinguished: industrial minerals (e.g. limestone, olivine, nepheline syenite, quartz and dolomite) dimension stone (e.g. larvikite, granite, marble and flagstone) raw materials for construction (sand, gravel, crushed rock and clay) metallic ores (iron, nickel and titanium oxide) fuel minerals (coal).
Dolomite as a mineral has very few uses. However, dolostone has an enormous number of uses because it occurs in deposits that are large enough to mine. The most common use for dolostone is in the construction industry. It is crushed and sized for use as a road base material, an …
Dolomite is a calcium magnesium carbonate with the chemical composition CaMg(CO 3) 2, constituting a rock-forming mineral found in abundance around the world.It has numerous commercial uses.

Atmospheric CO2 is sequestered within ultramafic mine tailings via carbonation of Mg-bearing minerals. The rate of carbon sequestration at some mine sites appears to be limited by the rate of CO2 supply. If carbonation of bulk tailings were accelerated, large mines may have the capacity to sequester millions of tonnes of CO2 …
