Where are the main sources of asbestos deposits in Shaanxi?
The proved reserves of brucite in the mining area are 7 million 800 thousand tons (the final geological survey report of 1960). It is the only super large fibrous brucite deposit found all over the world. Associated high-quality serpentine reserves reached 2.3 tons, proven chrysotile asbestos reserves of 1 million 700 thousand tons.With the approval of the state, the mine is undergoing a policy bankruptcy. Assessment by intermediary institutions, the southern Shaanxi asbestos ore realizable assets (excluding mining rights) 15 million 110 thousand and 800
The former is large in size and accounts for 93% of the total reserves in china. The metallogenic age of asbestos deposits is Precambrian, Paleozoic and Mesozoic, with Paleozoic mineralization as the most important. Main content of the project:The mine is located in Ningqiang County of Shaanxi province Miao BA Xiang, Dalin 22 km highway and Daan town of 108 National Highway and youngan railway connecting, convenient transportation. Mine open-pit mining, mining and built supporting concentrator three, handle 600 thousand tons of ore per year, with an annual output of 5 (product) products of more than 6500 tons, the following 5 products 20 thousand tons, 300 thousand tons of high-quality serpentine, products are mainly used for fiber cement, building insulation, rubber sealing products etc..
Asbestos, China asbestos mine resources are relatively rich. 15 provinces (autonomous regions) of China have asbestos deposits. Proven reserves of 45 mining areas, total reserves of mineral 90 million 610 thousand tons, ranking third in the world. Asbestos deposits in Qinghai are the largest, with reserves accounting for 64.3% of the total in China, followed by Sichuan and Shaanxi. Sichuan, Qinghai and Shaanxi, Mangya asbestos and asbestos asbestos ore mining in Ningqiang area. The genetic types of asbestos deposits in China mainly include two types of ultrabasic rocks and carbonate rocks.
