China Limestone factory-General Situation of Limestone Resources in China

China is one of the world's rich limestone mineral resources, in addition to Shanghai, Hong Kong, Macao, in the provinces, municipalities and autonomous regions are distributed.

According to the National Bureau of Building Materials Geological Center statistics, the national limestone distribution area of 438,000 KM2 (not including Tibet and Taiwan), about the land area of 1/20, which can be used as cement raw materials, limestone resources accounted for about the total amount of resources 1/4 ~ 1/3.

In order to meet the environmental protection, ecological balance, to prevent soil erosion, landscape tourism and other needs, especially with the construction of small towns in China continue to improve and implement the cement limestone for the exploitation will also be reduced.

The country has found cement and limestone mine seven or eight thousand, of which there are proven reserves of 1286, of which 257 large deposits, medium 481, small 486 (ore reserves of more than 80 million tons for large, 4000 ~ 8000 10,000 tons for medium-sized, less than 40 million tons for small), a total of 54.2 billion tons of ore reserves, of which limestone reserves of 50.4 billion tons, accounting for 93%; marble reserves of 3.8 billion tons, accounting for 7%.

The reserves are widely distributed in 29 provinces, municipalities directly under the Central Government and autonomous regions, of which Shaanxi Province has reserves of 4.9 billion tons, the highest in the country; the rest are Anhui Province, Guangxi Autonomous Region, Sichuan (including Chongqing City) Reserves of 34 to 3 billion tons; Shandong, Hebei, Henan, Guangdong, Liaoning, Hunan, Hubei 7 provinces have reserves of 30 to 20 million tons; Heilongjiang, Zhejiang, Jiangsu, Guizhou, Jiangxi, Yunnan, Fujian, Shanxi, Xinjiang, Jilin , Inner Mongolia, Qinghai, Gansu 13 provinces have reserves of 20 to 1 billion tons; Beijing, Ningxia, Hainan, Tibet, Tianjin, 5 provinces have reserves of 5 to 200 million tons.

Second, the market situation

From the current domestic and international demand for limestone, the world's annual demand is about 1.2 billion tons, but 80% for general purposes. High quality lime due to low resources, low yield, the market gap is large.

In recent years, the Asia-Pacific region because of its lack of domestic limestone resources, imports from China a year about 1.1 million tons of limestone. According to experts predict that the demand for high-quality limestone, the domestic will be 25 million tons per year, the Asia-Pacific region will be an annual increase of 300,000 tons.

From the domestic market, in the "second five" period, from the central to local accelerating the development of the western region, urbanization and the pace of the construction of new rural construction of the metallurgical building materials industry has played a direct role in promoting, which will stimulate Metallurgical building materials industry development, while a large number of national key projects will be started construction, and similar limestone is also high demand.

From the international market, China's limestone mineral resources, accounting for more than 64% of the world's total reserves, is an advantage of natural resources. Due to the limited mineralization of limestone minerals in most Western countries, cement production and limestone mineral resources are now limited, so its dependence on Chinese limestone is increasing and the export market continues to be bullish.

From the resource situation, the current relatively concentrated large-scale limestone mine, has been largely large cement enterprises and metallurgical enterprises monopoly, less and less new resources, in a sense, who holds the limestone resources, who To occupy the future of cement and steel market.

From the national and provincial policy point of view, have introduced the metallurgical and cement industry policy, in actively encourage the scale of new dry cement production and low energy consumption at the same time, the shaft kiln, high energy consumption, lack of reserves of resources and other metallurgy and Cement enterprises have been limited, but also from the environmental protection, resource and energy conservation, land use and production methods to improve the access threshold, which are for the development of large limestone mining industry provides a good environment.
