Magnesite can also be used as a binder in flooring material (magnesite screed). Magnesite and dolomite minerals are used to produce refractory bricks. Other minerals mined from the serpentine mass included cinnabar, chromite, magnesite, and jadeite. Mg are found in nature in many compounds such as dolomite, aragonite, magnesite (carbonate rocks). The mine also extracts pyrite, chalcopyrite, magnesite, native gold, and native silver. Salem district has one of the largest magnesite, bauxite and iron ore deposits in India. In these applications, the refractory materials are made from mixtures of chromite and magnesite. Salem has one of the largest Magnesite, Bauxite and also Iron ore deposits in India. Huntite often occurs in combination with other Mg/Ca carbonates such as dolomite, magnesite, and hydromagnesite. Gold, silver, limestone, coal seam gas, magnesite and gemstones are also mined. Magnesium-rich olivine (forsterite) favors production of magnesite from peridotite. Coal, iron ore, limestone, and magnesite deposits are larger than other mineral commodities. Magnesium carbonate is ordinarily obtained by mining the mineral magnesite. Chromite, talc, magnesite, copper and slate were also mined at Gundagai. The region is rich in minerals including iron ore, coal, magnesite, talcum and jade.
