subject: Existing Resources Distribution Of Uranium In China [print this page] China has discovered 59 uranium minerals, but only a few are usable in industry.Uraninite (UO2) is the most useful mineral. As it varies greatly in crystal behaviors as well as physical and chemical properties, geologists divide it into three minerals, uraninite, pitchblende and uranium blacks. Among them, pitchblend is of the greatest importance for industry, and therefore the major uranium mineral in present deposits explored. Next is the uraninite, which is found in pegmatitic uranium deposits in China. But they are not mined yet. Uranium blacks are not well developed in uranium deposits and so have no commercial values.The uranium minerals first found in China include brannerite, furongite, xiangjiangite, yingjiangite and tengchongite, most of which have no use for industry.Up to the present more than 200 uranium deposits have been explored in China, with substantial amount of resources submitted.China"s uranium resources are grouped into two categories, the known (discovered) and undiscovered (predicted), each of which can be subdivided into sub-categories. This classification is consistent with the international practice.The known resources of some uranium fields (deposits) are given as follows:Xiangshan uranium field, 26,000 tons of U;Xiazhuang uranium field, 12,000 tons of U;Qinglong uranium field, 8,000 tons of U;Chanziping uranium field, 5,000 tons of U;Chenxian uranium deposit, 5,000 tons of U;Tengchong uranium deposit, 6,000 tons of U;Lantian uranium deposit, 2,000 tons of U;Ili uranium deposit, 6,000 tons of U.The known resources consist of the reliable and prospective ones.1) The reliable uranium resources are those of high certainty, possessing the necessary data for designing a mine. These are mainly distributed in Hunan, Jiangxi, Guangdong and Guangxi, making up about two thirds of the total.Based on the price fluctuations in the world markets in the past ten-odd years and the recovery cost grade classified by the International Atomic Energy Agency, most of China"s reliable uranium resources have good or fairly good economic values, and can provide guarantees for the short- and medium-term development of nuclear power generation.As the professional manufacturer of complete sets of mining machinery, such as ore processing plantsand washing machine, Henan Hongxing is always doing the best in products and service.china cement mills:http://www.crusher-machine.com/23.html.Primary jaw crusher:http://www.hxjqchina.com/product-list_11.html.2) The prospective resources refer to those with a fairly high certainty, but are limited in quantity and of poor economic conditions.According to analysis of available data, China is a country rich in uranium resources in terms of the known resources. And, in view of China"s geological conditions for uranium metallogeny, the situation of uranium resources in the peripheral countries and the achievements made in uranium prospecting in recent years, many Chinese geologists are confident in finding more uranium resources in China, which they estimate to reach 1 to 2 million tons.The uranium deposits so far discovered are unevenly distributed. Although they are found in 23 provinces (regions) of China, they are concentrated in Jiangxi, Guangdong, Hunan, Guangxi, Xinjiang, Liaoning, Yunnan, Hebei, Inner Mongolia, Zhejiang and Gansu, among which the first four host most of the resources. In terms of the type of deposits, there are the following characteristics: the granite-type uranium deposits occur mainly in Guidong of Guangdong, Zhuguangshan of South China, Taoshan of Jiangxi and Beijiling of Northwest China; the volcanic-type ones mainly in Xiangshan of Jiangxi, Xiaoqiuyuan of Zhejiang, Baiyanghe of Xinjiang and the volcanic area on the north margin of the North China platform; the sandstone-type ones in the Ili basin of Xinjiang, the Xunwu basin of Jiangxi, the Hengyang basin of Hunan, the Jiangchang basin of Liaoning and western Yunnan Province; and the C-Si-mudstone-type ones in the Huangcai and Laowolong areas of Central China, Chanziping of Guangxi and the Ruoergai area bounded by Sichuan and Gansu.
