At present, magnesia has become the world's largest producer and consumer of building materials in my country. The output of light calcined powder, the main building materials products, such as cement, flat glass, building sanitary ceramics, stone and wall materials, has been in the forefront of the world for many years. Now the price of magnesium oxide on the market is generally increasing. In fact, this is not the result of market orientation, but the cost of producing magnesium oxide is constantly increasing, so we must know how to control the production cost of magnesium oxide?

For a long time, most of the dolomite in my country is separated from calcium and magnesium by calcination and carbonization. These processing methods have high energy consumption and pollution. leading to high prices of magnesium oxide. In recent years, due to the shortage of energy, the processing of dolomite needs to adopt more energy-saving and consumption-reducing methods. The effective separation of calcium and magnesium in dolomite is the key to making full use of it and reducing the price of magnesium oxide. Calcium and magnesium are separated by wet process. Calcium is made of calcium sulfate and magnesium is made of magnesium hydroxide. The intermediate calcium chloride is recycled, basically no three wastes are discharged, and the environmental benefits are obvious. At the same time, because the processes such as calcination and pyrolysis with high energy consumption are omitted, the energy consumption is greatly reduced, and the cost and price of magnesium oxide are further reduced, and the economic benefits are obvious.

Therefore, we must strengthen macro-control, and in accordance with the requirements of building a conservation-oriented society and developing a circular economy, encourage the development of advanced productive forces, accelerate the elimination of backwardness, and strive to adjust the structure, so as to build the building materials industry into a competitive industry of important raw materials and products, and realize the Big to strong transformation. On the basis of developing energy-saving building materials and establishing a circular economy, speed up the upgrading of building materials and realize resource and energy conservation.
