In salt lake brines, the content of potassium chloride is generally only 1/7-1/5 of magnesium chloride. For every ton of potassium chloride produced, about 10 tons of magnesium chloride hexahydrate will be co-produced. In the past, due to economic technical reasons, the utilization of magnesium chloride did form a scale, resulting in the increase of 120 million cubic meters of magnesium-rich old brine by-products in the production of potassium fertilizer, occupying a large amount of salt fields infiltrating the original brine Affects the production of potash fertilizer.

Therefore, many enterprises in Qinghai rely on the abundant local magnesium chloride brine resources, comprehensive utilization of raw materials potassium salt production, low production cost; high product purity, large production scale.

Due to the rapid expansion of production capacity, but the corresponding downstream market has been developed, the development of the magnesium hydroxide market has become an urgent task. Otherwise, it will cause overcapacity cause huge losses to the industry.

Since magnesium hydroxide exhibits excellent performance in flame retardant, air purification, wastewater treatment, etc., domestic magnesium hydroxide has the following potential markets to be developed:

1. Inorganic flame retardant products. Inorganic flame retardants can suppress the toxic harmful fumes produced during the combustion process. The proportion of inorganic flame retardant products in developed countries accounts for more than half, while my country currently has less than 10%. Magnesium hydroxide is a very high-quality inorganic flame retardant. However, due to technical economic investment in my country, the currently produced magnesium hydroxide inorganic flame retardant capacity is seriously insufficient, the supply of high-quality products is far meeting market demand. Every year, high-quality magnesium hydroxide flame retardants need to be imported to more than 10,000 tons, they are still increasing year by year. Therefore, research on high-quality magnesium hydroxide flame retardants is very promising.

2. Wastewater exhaust gas purification. Magnesium hydroxide can remove sulfur dioxide in flue gas, pigment in waste water, heavy metal ions, etc. It is a high-quality purification adsorption material. At present, 60% of magnesium hydroxide in developed countries can be used in the field of environmental protection. At present, the domestic flue gas desulfurization mainly uses the traditional lime desulfurization method, the magnesium hydroxide desulfurization method has been widely promoted. Therefore, in the field of environmental protection, magnesium hydroxide is of great use.

As a newly developed green industry in the 21st century, the development of the magnesium hydroxide industry will contribute greatly to achieving the goal of a beautiful China with a clean environment ecological civilization. At present, all parties are facing insufficient investment in the magnesium hydroxide industry, the market is mature enough, everyone needs to work together. long ago, magnesium hydroxide has been removed the list of hazardous chemicals, I hope this is a good start. my country is rich in magnesium resources, but it is a strong country in magnesium products. It is hoped that enterprises, scientific researchers government departments will work together to promote the development of the magnesium industry transform resource advantages into industrial advantages as soon as possible.
