According to the Department of Geology and Mining, Magnesite is used as refractory bricks for furnaces and has a wide range of usage in pharmaceuticals. The magnesite 

In the Jammu and Kashmir region, Magnesite deposits are primarily found in the Udhampur district, specifically in the Panthal area. These reserves are of high quality and are commercially significant for industrial applications. Why Magnesite is Important Magnesite is a mineral that remains stable at very high temperatures, which is why it is categorized as a "refractory" material. Refractory Bricks: Because it doesn't melt easily, it is used to line the insides of high-temperature kilns and furnaces in the steel and cement industries. Pharmaceuticals: It is used as an antacid (Magnesium Carbonate) and in the production of various mineral supplements.
