China has abundant calcium carbonate resources, which are distributed across the country. According to statistics from the National Building Materials Bureau of Geology Center, China has 438,000 square kilometers of limestone distribution areas, accounting for about 1/20 of the country's total land area. These resources can provide about 1/4 to 1/3 of the raw materials needed for cement production. A survey found over 7,000 limestone minesites nationwide, with proven reserves of 1,286 billion tons, including large, medium, and small deposits. Total reserves are estimated at 54.2 billion tons, with 50.4 billion tons of limestone and 3.8 billion tons of marble. Reserves are spread across 29 provinces

1. China Resources and the Geographic Distribution of Calcium Carbonate:
calcium carbonate is highly versatile valuable resource: China is one of the richest country of
mineral resources in the world. In addition to Shanghai HongKong, Macao. In the province,
municipalities and autonomous regions are distributed. According to the former National Building
Materials Bureau of Geology Center statistics, National limestone distribution area of 438,000
KM2(not including Tibet and Taiwan). Land area accounts for about 1/20, which can be the raw
material for cement limestone resources to do about the total amount of resources 1/4 to 1/3. In
order to meet the requirements of environmental protection, ecological balance, preventing soil
erosion needs. tourist and other aspects. Especially with our small towns planning and
implementation improvement continuously. mined limestone for cement will reduced. National
Cement limestone mine sites have been found seven or eight thousand, which has proven reserves
of 1286. where large deposits 257,481 medium-sized and 486 small-sized(more than 80 million
tons of ore reserves for large,medium-sized 4000 to 80 million tons, less than 40 million tons for
small). Total reserves of 54.2 billion tons of ore holdings, including limestone reserves of 50.4
billion tons. Accounting for 93%,3.8 billion tons marble reserves, accounting for 7%. Reserves are
widely distributed 29 provinces in addition to Shanghai, municipalities and autonomous regions.
Shanxi Province reserves of 4.9 billion tons,the highest in the country. the rest were in anhui,
Guangxi, Autonomous Region, Sichuan(including Chongqing)province. Each reserve is 34-3
billion tons. Shandong, Hebei, Henan, Guangdong, Liaoning, Hunan, Hubei Province, each 7
