How many tons of ore can produce one ton of dead burned magnesia?

How many tons of ore can produce one ton of dead burned magnesia? It takes two tons of magnesite to produce one ton of dead-burned magnesia. Why can two tons of ore produce one ton of dead-burned magnesia, because the content of magnesite is 46%, and two tons of magnesite with a content of 46% are equal to 92 %, so two tons of 46% magnesite can produce 92% dead burned magnesia, and the remaining 8% is silicon, calcium, iron, aluminum, caustic soda, magnesite. The main components are magnesium carbonate, magnesium carbonate After being calcined in iron kiln, it is decomposed into magnesia. Dead burned magnesia is a kind of basic refractory raw material. The refractory temperature of the product can reach above 1800 ℃.
