More than 40 years ago, a pure white stone was discovered and people began to think about its application. Today, this white stone is ground into particles smaller than 3 microns, which has been sold for thousands of dollars per ton, up to a maximum of 10,000 yuan. However, the pace of exploration and development has not stopped because of this. In the deep mountains of Xianfeng County in southwestern Hubei, the stone processing industry is heading for an annual output value of 1.5 billion yuan.
Stone grinding powder can be sold for 10,000 yuan per ton
According to Director Wang of the Zhongbao Industrial Park in Xianfeng County, Hubei Province, who has been dealing with white stone for many years, the name of this white stone is called calcite, which is white in color and consists of fine rhomboid material. The main component is calcium carbonate, which is used in industry. Very wide.
Song Donghua, head of Jiebao Mining Co., said: "This material is included in many products. In addition to wall paint for home decoration, heavy calcium carbonate can also be widely used in inks, dyes, plastic doors and windows, glass, automobiles. And many other industries."
In Song Donghua's Jiebao Mining Company, the white stone of a car was transported into the factory. After removing the impurities, these white stones will be sent to the production line and ground to a heavy calcium carbonate powder by machine. Depending on the size of the particles, the price of the product is also quite different. Taking the company's products as an example, a powder with a fineness of 400 mesh (a unit of mass size) can be sold for 300 yuan per ton; a powder with a fineness of 4000 mesh can be sold for 1,500 yuan per ton; The price of products such as high-grade cosmetics can even reach 10,000 yuan per ton.
Song Donghua discovered that although the price of this powder is not cheap, the market is getting bigger and bigger. In April last year, his factory was rebuilt and expanded, and the current design capacity reached an annual output of 150,000 tons. Previously, his clients were mainly concentrated in Sichuan, Chongqing and other places around Enshi, and since this year, many coastal customers have also found him.
20 years of history stone completes "deformation"
However, the development of white stones was another scene decades ago.
Originally, white stone was used as an ornament, and later it was widely used in various local constructions, terrazzo floors, exterior wall decoration and other projects. "The ones that can use white stones are all graded buildings." The locals recalled.
Because it is widely used in the construction industry, this white stone was also "worthy at the time", which can be sold for 50 yuan to 70 yuan per ton. In the late 1990s, with the acceleration of the Three Gorges immigration process, the construction boom brought about by the relocation of immigrants made the sales of Xianfeng's white stones even larger. Once, a boss in Chongqing said to Song Donghua and other local stone owners in Xianfeng County: "You are too wasteful to develop this way. You can deep-process white stones into heavy calcium carbonate, and the added value of the products will be higher."
A word to wake up the dream. Xianfeng’s white stone began its own “deformation record†and its value began to increase exponentially. Starting with a product with a fineness of 200 mesh, Jetway Mining and local development companies have completed several rounds of technical upgrades with a maximum fineness of 8,000 mesh. Song Donghua said: "To what extent, 3000 mesh is equivalent to only 3 microns per particle, while human hair is about 70 microns, that is, the fineness of these powders is only 1/20 of the hair."
Stone development achieves 1 billion yuan output value
After 20 years of transformation, the white stones of Xianfeng are no longer "flower vases", and become more "connotative".
However, local governments and entrepreneurs such as Song Donghua are still not satisfied with the current development status. After a more in-depth study, they hope that this white stone can contribute more value to the local.
After all, this is a huge wealth left by nature for the locals. They don't want to waste easily. According to the exploration of relevant departments, there are 14 white calcite ore belts in Zhongbao Town, Xianfeng County, with a reserve of 10 million cubic meters. It can be mined for 100 years based on current production.
After 23 years of dealing with white stones, Song Donghua and more than 10 local entrepreneurs began to transform their factories and mines and settled in local industrial parks. After the hardware facilities were improved, Song Donghua began to brew into the higher-end industrial chain. "We can't be satisfied with working for downstream manufacturers." Song Donghua is quite confident about the quality of local white stones. With the good quality of the products, he began to contact with downstream companies. Because the strength of the enterprise is not enough, in the development strategy of Song Donghua, the first step is to introduce the downstream enterprises and be able to “borrow the eggsâ€. At present, he is in contact with a well-known paint company in China, hoping to introduce this company into the industrial park, and the two sides will jointly set up factories.
At the same time, he is also negotiating with a paper company to prepare a joint production of stone paper made from white stone. This kind of paper can be widely used in high-end markets such as calendars, not only to avoid felling trees, but also to automatically degrade into powder, and can be recycled for secondary use.
Relevant persons from the local government departments said that due to the inconvenient transportation in Xianfeng County, although the quality of calcite is very good, the excessive transportation cost has become the main obstacle to its departure from the mountains, and the introduction of upstream and downstream enterprises can solve this problem well. A problem.
In fact, the development of white stone is only a microcosm of the development of Xianfeng stone industry.
In Xianfeng, there are abundant stone resources. The initial proven marble reserves are about 29.09 million cubic meters, the sandstone reserves are about 38.4 million cubic meters, the calcite reserves are about 10 million cubic meters, the kaolin reserves are about 800,000 tons, barite, limestone, page. Rocks have a certain amount of reserves.
In the industrial park less than 10 kilometers away from the county, more than 10 stone enterprises are stepping up production. The huge rocks are cut from the mountain, processed into one floor tiles, wall tiles, and some are processed into stone carvings. Under the joint efforts of these enterprises, Xianfeng County has formed an annual processing capacity of 3 million square meters of stone processing capacity, and annual sales have exceeded 1 billion yuan. It is expected that this number will double again in the next five years.
