The raw material of magnesium oxide can be individual into two types

At present, the raw material to produce magnesium oxide can be divided into two types all over the world: the first one is solid raw mineral material high contamination. These solid raw mineral material include dolomite, magnesite and so on. It can produce magnesium oxide with the content of 93-95%. The another type is used in many advanced countries. It can made high purity magnesium oxide with the content over 96-99%. Because our country mainly uses solid raw mineral material to produce magnesium oxide, these magnesium oxide’s quality is poor. In recent years, China introduces foreign advanced equipment, but the products still focus on the content lower 96%. So it is hard to achieve high purity requirement. Nowadays, the vast majority of Chinese production capacity is in 300 to 500 class in tons. Very few enterprise can achieve kiloton class. The largest is Hebei Meishen Technology Co., Ltd. In foreign, especially in the USA and Western Europe, their single equipment ability are over the class of ten thousand tons. The production scale of program unit is 5000 tons, it belongs to large scale. Although the achievements in scientific research of careful magnesium oxide product continuously emerging in recently, the kind and quality still can not meet the market demands, much less for foreign export. The few fine product also affects the economic benefit of magnesium salt enterprises. At present, the serious of high purity magnesium oxide’s industrial manufacturer in domestic is still in researching and developing, this serious of products’ functionalization, customization and fining have already been the production key point from the research and development of various countries.
