Technology Progress and Development Trend of Preparing Magnesium Oxide from Magnesite

This is an article in the field of mining engineering. Magnesite in China is rich and good in quality. Its mineral quantity and grade rank the first in the world. It is widely used as the raw material for the production of magnesium oxide in industry. The change of microstructure of magnesite during calcination is the key to performance the properties of magnesia products. Taking this as the starting point, the technical progress of preparing high-performance magnesia products from magnesite is summarized firstly. Then, according to the restrictive factors of industry development, this article analyzes the future development trend of this field briefly.
