Kaolin is not a non renewable resources ah?
Resource characteristicsChina kaolin ore types in sandy kaolin, which accounts for more than 60% of the total reserves of kaolin; soft and hard kaolin total reserves were 6% and 5%; other types of kaolin accounted for 27% of total reserves.From the perspective of the quality of the ore, most of China's kaolin ore for ceramic soil, Al2O3 content (grade) is generally about 20%, up to more than 38%, the minimum of not less than 10%. In the past, China's paper coating and filler grade kaolin is relatively short, in 1989 the new Guangdong kaolin mine in Maoming, not only a huge reserves, but also the quality of the ore texture, up to the quality level of the scraper coating. Its discovery, so that China has access to high-quality kaolin resources in the list of major powers. Kaolin reserves in the country, the paper grade kaolin accounted for 41.06%, ceramic grade kaolin accounted for about 48.35%, such as white cement grade, rubber grade and electric porcelain kaolin together accounted for only about 10.59%.
Resource statusChina is one of the world's rich kaolin resources in the country, as of the end of 1996, to maintain the kaolin ore producing area of 208, to retain ore reserves of T, B + C level of 344 million 970 thousand T (table 4.22.10). The ore reserves of more than 1 million T large and medium-sized mining area of 97, reserves of 1 billion 344 million 102 thousand T (B + C 302 million 307 thousand T), accounting for 94% of total reserves, small 111 mining areas, reserves of 87 million 590 thousand T (B + C 42 million 663 thousand t), accounting for 6% of total reserves.In addition, China also found more than and 600 kaolin deposits, according to the analysis of the Ministry of Geology and mineral resources "mineral resources strategy" (1984), estimated Chinese kaolin resources in more than 1 billion 200 million T. According to another report on the recent coal department forecast Chinese northern Carboniferous Sedimentary type third period coal series kaolin in the Jurassic strata, the potential resource of up to 18 billion T, the total resources of Chinese kaolin thus may be more than 19 billion T, after the United States and the former Soviet Union, Britain, ranking fourth in the world.
China kaolin deposits are mainly small and medium-sized. In 208 mineral holdings, according to the "standard" geological prospecting kaolin deposit scale division standard, large ore reserves of more than 20 million T Jiangsu Wuxian view of mine (34 million 211 thousand T), Fujian Longyan East West mining area (51 million 720 thousand T), Jiangxi Guixi county to mine (28 million 437 thousand T), ridge mine in Xingguo County of Jiangxi province (21 million 674 thousand T), Guangdong Maoming Shan Ge ore (286 million 333 thousand T), Guangdong Maoming Datong mine (56 million 610 thousand T), Guangxi Hepu County Cross Road North pond mine (52 million 941 thousand T), Guangxi cross road District Pang Wu ore (25 million 781 thousand T) and Shaanxi County of Fugu Sea Temple Village (mine 351 million 50 thousand T), Shaanxi Fugu County Sha Chuan Gou mine (20 million 127 thousand T) a total of 10 ore reserves is 2000 ~ 5 million T 25 large ore deposit; ore reserves of 5 million t to 1 million T and 62 ore; ore reserves of less than 1 million T There are 111 small mines. Has the exploration of geological work in large deposits in 10, detailed investigation of the 16 census, there are 9 medium-sized deposits in exploration work; 9, detailed investigation of the 29 census, there are 24 places; exploration work in small deposits 9, detailed 53 the 42 census.
