How many tons of ore can produce one ton of calcined magnesia?

How many tons of ore can produce one ton of calcined magnesia? It takes two tons of magnesite to produce one ton of calcined magnesite. Why can two tons of ore produce one ton of calcined magnesite? Because the content of magnesite is 46%, and the total content of two tons of 46% magnesite is 92%, so two tons of 46% magnesite can produce 92% of calcined magnesite. The remaining 8% is silicon, calcium, iron, aluminum, caustic soda, and the main component of magnesite is magnesium carbonate, Magnesia carbonate is decomposed into magnesium oxide after calcination in a iron sheet kiln. The re calcined magnesia is an alkaline refractory raw material, and the product's fire resistance temperature can reach above 1800 ℃. The re calcined magnesia products are widely used in magnesia bricks, magnesia alumina bricks, magnesia chrome bricks, gunning materials, castables, dry materials, coating materials, furnace repair materials, asphalt, casting, fire protection and insulation materials, flux accessories, electrical steelmaking furnaces, heating furnaces, rotary furnaces, steelmaking Electric furnace bottom and ramming furnace lining.
