Stone resources in Xinjiang are mostly distributed on barren mountains and gobi beaches. The amount of ore body stripping is small, which is suitable for large-scale mining and has little impact on the environment. At present, some large stone enterprises in the southeast coastal areas of China are increasing their investment in Xinjiang stone equipment, technology and capital, which will strongly promote the rapid development of Xinjiang stone industry. In addition, the railway network in some major stone producing areas in Xinjiang is underdeveloped, so the expensive transportation cost will become the bottleneck of controlling the cost of stone in Xinjiang in recent years, which should be highly valued by the mine developers.
Guangxi: good quality of red varieties and increased profits
A few years ago, Cenxi red and Maple leaf red granite plates in Guangxi were very popular in domestic and overseas markets. In recent years, due to insufficient investment and other reasons, compared with large stone provinces such as Fujian, Guangdong and Shandong, the upgrading of technology and equipment has lagged behind, leading to the absence of the scenery of granite decorative materials such as Cenxihong. According to the analysis of the authority in the industry, the stone varieties developed in Guangxi, such as Sanbao Red and Guilin Red, are superior in stone quality, but they cannot sell well in the market. The main reason is that the processing technology is backward and the product grade is low.
Not long ago, Hezhou, Guangxi, invested 1 billion yuan to build a large stone industry, increased the investment in the mining and processing of white marble and other varieties of granite, and started the "big move" of building a first-class stone base, which seems to make people hear the call for the revitalization of Guangxi stone.
Yunnan: High quality sandstone and new marble are welcomed
Yunnan is the hometown of marble. However, in the past ten years of rapid development of China's stone industry, when selecting marble for architectural decoration stone, it often refers to Italy, Beijing Fangshan, Guangdong Yunfu, Sichuan Baoxing, Shandong Pingyi and other producing areas. As the hometown of marble, Yunnan seems to be rather neglected. Of course, Yunnan marble still retains an indispensable position among antique furniture, natural stone paintings and various handicrafts. In recent two years, many famous varieties in Yunnan have been gradually developed and welcomed by the market, such as Baoshan beige, white crabapple, colorful jade, Cuan jade and other famous marble varieties.
In addition, Yunnan sandstone is an ore body formed by hundreds of millions of years of natural sedimentation, with large reserves and many varieties in Wuding County. At present, there are many kinds of sandstone building decorative materials in Yunnan, such as yellow wood grain, tree ring grain, beech grain, birch grain and so on, with huge reserves. Sandstone mining has formed several large-scale enterprises in Yunnan, led by Yunnan Lishi Stone Company, with an annual output of 200000 square meters.
It is reported that the development of sandstone has been listed as a key project in Yunnan Province, which will lay a solid foundation for Yunnan stone to rebuild its brilliance.
Sichuan: large resource reserves, multiple varieties and superior mining conditions
In Ya'an Prefecture, Sichuan Province, Kangding County, Ganzi Prefecture and other places, white marble mineral resources are extremely rich and of good quality, such as "Baoxing White", "Lotus White", etc., and its recoverable amount is rare in China. Sichuan is also rich in granite mineral resources. For example, the rice Yilv and Panzhihua Xilan that have been put into mining in Xichang and other regions are high-grade varieties. In addition, the sandstone, which has become the new favorite in the market, also has a large amount of storage, and has the advantages of wide distribution and superior mining conditions. Experts believe that the red wood grain and green sandstone produced in Sichuan are of good texture and are popular fashion decorative materials in the market, with good development prospects.
At present, although Sichuan has rich varieties and huge reserves of mineral resources, the scale of mining and processing is relatively small. The annual mining volume of granite and sandstone is only a few thousand cubic meters, which is in a situation of high reserves and low production. The mining and processing of white marble in Baoxing, Sichuan has begun to take shape, and has preliminarily formed a relatively complete industrial chain from mining, plate processing, profile processing to product sales.
Inner Mongolia: convenient transportation, good ore body and large development space
Jiachifeng, Liangcheng, Fengzhen and other major stone producing areas in Inner Mongolia are rich in stone varieties. They are famous at home and abroad for their black granite products with perfect quality, and have prominent advantages in rare varieties. The black granite rich in Fengzhen is called "Fengzhen Black". The unique black granite variety in Linxi County, Chifeng City - Oriental Jet Jade is as hard and dense as ink. Its weathering resistance cannot be compared with any decorative stone, and it has become a rare and precious stone variety in the world.
In recent years, red and yellow granite inlaid with yellow flag in Inner Mongolia Alashan League and Xilingol League, such as red rose, gold rose, Alashan yellow, star diamond, etc., have formed mass production, which has the advantages of good texture, good mining integrity, small color difference, etc., and gradually become the main stone production area in Inner Mongolia, which deserves the attention of the industry.
It is understood that in recent years, the relevant government departments in various stone producing areas in Inner Mongolia have successively introduced a number of preferential policies for attracting investment. In addition, the relatively cheap labor force, investment and development are just in time. The train and automobile transportation conditions are increasingly mature, which is very suitable for the development of the stone industry.
