Thus, this increased the potential of rock strata as good oil, gas, and groundwater reservoirs and certain types of ore deposits. In the 19th century, the dolomite mountains were one of the great geological ...
Dolomite, or dolostone, is a carbonate sedimentary rock made mostly from the mineral dolomite, CaMg(CO 3) 2. It commonly occurs in association with limestone and shares many of the same properties, but reacts only weakly …
Sedimentary rock - Limestones, Dolomites, Carbonates: Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the secondary alteration or …
The extraction of magnesium from dolomite ore can be done by leaching process. The magnesium can be extracted from dolomite by using hydrochloric acid solutions. Carnallite is a reddish rock of magnesium and potassium. This is mainly found in German and Spain. It is an important source of potassium.
