Dolomite (mineral) Wikipedia

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smeltingof iron and steel. Large quantities of processed dolo

magnesium processing Techniques & Methods Britannica

The chlorine can be reused in the dehydration process. Thermal reduction. In thermal production, dolomite is calcined to magnesium oxide (MgO) and lime (CaO), and these are reduced by silicon (Si), yielding magnesium gas and a slag of dicalcium silicate. The basic reaction, is endothermic—that is, heat must be applied to initiate and sustain it.
