Dolomite resources are found in all provinces and regions of China, especially Shanxi, Ningxia, Henan, Jilin, Qinghai, and Guizhou. ... Table 1.6 shows the compositions of dolomite ores mined from several typical dolomite mining areas.
Magnesium in turn is a major element in dolomite and thus, the study of dolomite magnesium isotope ratios (δ 26 Mg dol) is a potentially promising research field, but one that is insufficiently explored. Here we suggest that dolomite Mg isotope ratios must be added to the list of proxies when dealing with recent and fossil dolomites.

Magnesium oxide suitable for the use in basic refractories was prepared from dolomite (CaMg(CO 3) 2) by hydrochloric acid leaching, precipitation with CO 2 and thermal hydrolysis. Leaching of the dolomite ore in aqueous hydrochloric acid solution was investigated with respect to the effects of time on dissolution of the dolomite sample.
The term dolomite is used both for the mineral dolomite (calcium magnesium carbonate [CaMg(CO 3) 2]) and for the rock dolomite, which consists mostly of the mineral dolomite. Dolomite rock is sometimes termed dolostone to distinguish it from the mineral dolomite, but the more confusing terminology is the more prevalent.

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. Dolomite mineral is rarely found in modern sedimentary environments; however, dolomite rocks (dolostones) are common in geological history.
Baymag Inc. produces magnesite at the Mount Brussilof mine from Cambrian limestones in which magnesium has replaced calcium. The genesis of the deposit is thought to be mineralogical replacement or molecular substitution. As such, the process occurred when a fine-grained dolomite CaMg(CO3)2 was substituted by a coarse-crystalline magnesite MgCO3.
