Which areas rich in limestone resources in China?
China is one of the countries in the world that are rich in limestone resources. Limestone has been found in all provinces, municipalities and autonomous regions except Shanghai, of which 22 provinces and autonomous regions have total limestone resources of 12,000~13,000 billion tons, including 3,000~4,000 billion tons of cement limestone. By the year of 1997, about 7,000~8,000 cement limestone occurrences had been discovered in China and retained reserves were obtained for 1,269(265 large-sized, 498 medium-sized and 506 small-sized) of them. The country’s total retained reserves of cement limestone (category B+C+D) are 54.27 billion tons (limestone: 50.79 million tons; marble: 3.48 billion tons).
Among the total retained reserves of cement limestone, category B+C makes up 59%. Exploration and detailed reconnaissance have been carried out for 82% of the occurrences including the present major mines, and the reserves (category B+C) of the major large and medium-sized mines amount to 80% of the national total.
667 (118 large, 256 medium-sized and 293 small-sized) occurrences with retained reserves have been utilized and their retained reserves are 28.6 billion tons, making up 53% of the total. They are distributed mainly in Shandong, Shaanxi, Hebei, Anhui, Zhejiang, Heilongjiang and Liaoning provinces. The retained reserves can meet the requirements of the present large and medium cement plants until 2010 and in the ensuing period of time. 560 (137 large, 225 medium-sized and 198 small) occurrences can be selectively utilized in the near future, whose total retained reserves are 23.8 billion tons, accounting for 44% and mainly distributed in Shaanxi,Guangxi,Henan,Guangdong,Anhui,Hunan,Guizhou and Chongqing. Of the total 1269 occurrences, 42 (10 large, 17 medium-sized and 15 small) are not ready to exploit at present. They have retained reserves of 1.9 billion tons, accountinf for 3% of the total, and are distributed mainly in Guangxi, Qinghai, Sichuan, Chongqing and Fujian.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,jaw crusher,vibrating screen Welcome all of you to visit our official website.ore vibrating feeder:http://www.hx-crushers.com/p22.html
