Magnesium (Mg) is the eighth most abundant element and constitutes about 2% of the Earth''s crust, and it is the third most plentiful element dissolved in seawater. Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, and olivine are of commercial importance. Magnesium and other magnesium compounds are also produced from seawater,
Extraction from Dolomite and Magnesite Ore . Electrochemical processes are used to extract the metal from dolomite and magnesite ore. When dolomite is crushed, roasted and mixed with seawater in large tanks, magnesium hydroxide settles to the bottom. Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride.
Magnesium is chiefly obtained by electrolysis of magnesium chloride, which can be obtained in virtually unlimited quantities from the oceans. It is obtained from salt lake brines in the USA. Magnesium is also obtained in smaller quantities from the magnesiumbearing minerals dolomite, magnesite, kieserite and .
Magnesite is an important ore of magnesium, and used as insulating material. White Magnesite is also used as a minor collectors gemstone, polished into beads and spheres as well as carved into figures. These forms of Magnesite often have black or brown rock veins running through the mineral.
Calcite
The company''s major deposits and production facilities are located in the Eskisehir area Kümbet, Erenkoy in the CentralWestern part of Turkey. The deposits consist of three main concessions totaling,5 hectares with significant proven reserves. Mining of magnesite ore (cryptocrystalline type) is carried out open cast.
Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby.
Ryongyang Mine is the largest magnesite mine in North Korea and one of the largest in the world. However, satellite and ground imagery show the infrastructure and technology in use at the mines is dated and obsolete when compared to world standards.
Aug 16, 2019· The mining and export of magnesite, and the domestic production of products from it, are important to the North Korean government and economy as indicated by the praise the Ryongyang Mine and other magnesite mines and production facilities have routinely received from Kim Ilsung, Kim Jongil, and Kim Jongun.

Magnesite is an important industrial mineral composed of magnesium carbonate (MgCO 3. Pure magnesite is theoretically % magnesia (MgO) and % carbon dioxide (CO 2).. It is the source of twothirds of the world''s magnesia (MgO); 25% is extracted from sea water, with the balance coming largely from brines.
Mining of magnesite began at the Kunwarara mine in Queensland in 1991 at the KG1 open pit that also contains the beneficiation plant. The KG 3 open pit came online eight years later, in 1999 and the following year, 2000, the KG2 open pit also began production. The Oldman South and Oldman North deposits were developed in later years.
MINING AND CONCENTRATING : Both dolomite and magnesite are hauled out and concerted by conservative methods. Carnallite is hauled out as ore or alienated from other salt amalgams that are brought to the exterior by solution mining. Naturally happening magnesium including brines are determined in large ponds by solar desertion.
