Bentonite is a natural mineral soil, which is widely distributed and has large reserves in China. Its important ingredient is montmorillonite. So, how much is the content of montmorillonite in bentonite in various regions of China, this question is not easy to answer in one sentence. This is because the quality of the raw ore varies greatly from place to place, with high levels in some places and low levels in others. Here, the editor will sort out and tell you the basic situation of montmorillonite content in the main bentonite producing areas in China.
1. Liaoning bentonite is mainly distributed in Jianping, Kazuo, Beipiao, Montenegro and other places. Among them, Jianping is the most representative, and its influence in China is also the largest. The montmorillonite content of bentonite from Jianping County, Liaoning Province is generally 58%-95%. It is a relatively high-quality mineral soil in China. 2. Inner Mongolia originThe bentonite production area of Inner Mongolia is mainly concentrated in the Chifeng area, and the raw ore quality in this area is also a high-quality mining area in China, with montmorillonite content of 55%-94%. The finished products are mainly for medicine, engineering slurry, feed and other industries. 3. Hebei bentonite minerals are mainly concentrated in Zhangjiakou area, and some minerals are also in Handan area. The montmorillonite content of Zhangjiakou bentonite is 55% on average, and there is no raw ore with high content. The finished bentonite products in this region are mainly concentrated in the production industry of some paint putties at the middle and low end. 4. Shandong bentonite is mainly distributed in Weifang area, Jining Surabaya has some low-end minerals and Rizhao Wulian also has some minerals. The average level of bentonite montmorillonite content in Weifang area is 55%, the montmorillonite content in Surabaya is generally 45%, and the content of Rizhao Wulian is 50%. Therefore, it can be seen that the quality of bentonite in Shandong is at the middle and low end of the dry level. 5. Henan OriginHenan bentonite is mainly concentrated in Xinyang, and the minerals in this area are mainly underground mining, so the mining cost is much higher than that in the northern region. The montmorillonite content is generally 58%-67%. Compared with Hebei and Shandong, it is slightly better, but the reserves are not very large. 6. Zhejiang OriginZhejiang bentonite production area is mainly concentrated in Huzhou area, and the raw ore reserves in this area are not very large, mainly white bentonite. Its montmorillonite content is generally 60%. The finished bentonite products are generally mainly activated clay and organic bentonite. There is also the production of bentonite for some engineering muds. 7. Guangxi originThe bentonite production area of Guangxi is mainly concentrated in the Ningming area, which has many similarities with the Xinyang area of Henan, which belongs to underground mining and has a large production cost. However, the montmorillonite content is not very high, generally around 55%. It is mainly used to produce engineering mud bentonite. The above is the montmorillonite content of the main bentonite producing areas in China. The production areas with relatively high montmorillonite content are mainly Liaoning and Inner Mongolia.
