China's bentonite rich in resources, proven geological reserves of bentonite mining area of about 86, has proven reserves of more than 5.087 billion t, is expected to more than 8 billion tons of resources, total reserves accounted for 60% of the world's total, ranking first in the world Bit.
At present, China's bentonite production of about 400 million tons / year, of which the largest consumption is the casting industry accounted for about 44%, drilling mud accounted for about 28%, iron ore pellet is about 18%, oil decolorization of about 8% In the petrochemical industry, agriculture, building materials and so on.
At present, in the Chinese Raymond Mill market, calcium bentonite supply is oversupply; sodium bentonite because of better stability, market value is higher; active clay is widely used, but by the impact of raw materials and environmental protection, production development is slow, can not meet the market demand. Organic bentonite due to process, production equipment and quality instability and other factors, while the price of organic cover agent, resulting in organic bentonite production costs are higher, the development of slow. At present, high-quality organic bentonite is still the main import.
In the past two years, the production and technology of organic bentonite have developed rapidly. Due to the implementation of the national mineral protection policy and the injection of foreign capital, the price of bentonite ore has been improved, and the iron and steel enterprises have produced no production The At present, the price of organic bentonite, cheap in 10,000 yuan / t or so, high to reach 3-4 million yuan / t. With the continuous improvement of organic bentonite production and processing technology and the interests of the drive, making more bentonite enterprises began to produce organic bentonite. Zhejiang Anji Tianlong Organic Bentonite Co., Ltd. has become the world's largest organic bentonite processing base, the annual output close to 5-7 million t.
The next few years, the domestic market demand for organic bentonite will reach 30-40 million tons / year, while the organic bentonite will be towards the refinement, serialization, functional and other direction of continuous development. Actively carry out research on organic bentonite production technology, accelerate the industrialization of industrial transformation, expand the application of organic bentonite, organic bentonite to achieve high efficiency, high value-added comprehensive utilization of organic bentonite industry will be the main direction of development.
