As we all know, diamonds are the most valuable and hardest gemstones with high commercial value. In order to be able to make diamonds by man-made methods, many scientists in the world have struggled for more than 60 years; and the wisdom of the Mongols has collaborated with other scholars to overcome this world problem. Dr. Lamu Surong’s scientific research proves that diamonds can be extracted from limestone.
Although China has always had the title of a resource-rich country, with the exploitation and waste of resources, many resources have begun to appear in reserve. Limestone is a big example. According to statistics, the reserves of Chinese limestone are only enough for 25 years, while the reserves of coal are enough for more than 100 years.
As early as 2005, the proven reserves of limestone in the country were 75 billion tons, of which only 39 billion tons were economically exploited (North City Planning and Design Institute, 2007). In 2007, the country produced 1.36 billion tons of cement and consumed about 1.65 billion tons of limestone. As long as the consumption is 23.6 years, the limestone with economic exploitation value will be used up, and the proven limestone mine is only used. It is enough to mine for 45 and a half years.
According to industry insiders, limestone is the second largest non-metallic mining product after coal. The reserves are far less than coal. The damage to the surface and landforms of mining is far more than that of coal mining, and it cannot be recovered.
In fact, limestone is a non-renewable resource that is extremely versatile and is the trade name for limestone as a mineral raw material. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide. It is an indispensable flux limestone in the metallurgical industry. High-quality limestone is widely used in the manufacture of paper, rubber, paint, paint, medicine, cosmetics, feed, sealing, bonding, polishing and other products after ultra-fine grinding. Among them, the ratio of limestone consumed by cement production to limestone produced by building stone, lime production, metallurgical flux and ultrafine calcium carbonate is about 1:3.
According to the China Securities Journal, the invention of new technologies will stimulate the imagination of the market. Limestone is connected with the extremely high value of diamonds, which will undoubtedly further stimulate the market's interest in listed companies with limestone mining resources, such as Feng Cement, Yinglite and Fujian. Cement and Ningxia building materials.
