1. The flotation method is one of the main purification methods for processing light burnt magnesia balls. For gangue minerals such as talc, quartz and other silicate minerals, the flotation is usually Under the natural pH of the slurry, the addition of amine cationic collectors and foaming agents can achieve good results and increase the purity of light burnt magnesia balls to 95%-97%.

Second, it is light burning: magnesite is calcined at a temperature of 750-1100℃, called light burning; its product is called light burned magnesia powder. Since the burning loss of magnesite is generally about 50%, the mgo content in the ore can be almost doubled through light burning. In this sense, light burning is a means of mgo enrichment. In addition, light burning is also a preparatory operation for magnesite thermal separation and some heavy separation. Light burned magnesia has high activity and is an ideal raw material for the production of high-density magnesia.
3. Thermal separation method: using the difference in thermal properties between magnesite and talc, the difference in density and hardness between the two is caused after calcination, and then the mineral is obtained by selective crushing and simple screening or classification Separate.
Light burnt magnesia balls are used to make refractory materials. In the United States and most countries that consume magnesium products, the steel industry is one of the consuming industries. The light burned magnesia balls made from magnesite ore, sea water, salt lake or well salt are mainly used in the manufacture of refractory products for metallurgical furnaces. Light burnt magnesia balls are widely used in various fields.
In short, with the development of the new chemical industry, the raw material of light burned magnesia balls will become a more popular demand target, and the wholesale volume of light burned magnesia balls will increase accordingly.
In addition, with the advent of autumn, the weather will gradually cool down until the cold and mid-winter, the wholesale volume of light burned magnesia balls may rise slightly, and the price of light burned magnesia balls will also increase. The specific trend remains to be seen.
