The mineral resources of glass siliceous materials are abundant in the world. For example, the United States, Russia, Japan, Germany, the United Kingdom, Canada, India, Australia and other countries have more siliceous minerals, mostly quartz sand mines, and a few countries also have quartz sandstone , quartzite , and Weijing granite quartz blocks. And Yunyingyan and other mines, but lack of reports on resources and reserves.
China is one of the countries with rich mineral resources in the world of glass siliceous materials. Due to the wide distribution of metamorphic rocks and sedimentary rocks rich in quartzite and quartz sandstones, the long coastline of the east is distributed with granite or mixed rocks as sources of silica sand, and there are many inland rivers and lakes distributed. These are siliceous raw materials. Favorable conditions. According to the prediction of the Geological Research Institute of the National Building Materials Bureau, the mineral resources of China's glass siliceous raw materials can reach 29 billion tons. By the end of 1996, there were 192 mineral deposits with proven reserves in the country, and the accumulated B+C+D ore reserves were 399.694 million tons. Among them: 70 quartz sandstone mines, proven ore reserves of 610.1 million tons, 35 quartzite mines, proven ore reserves of 225.934 million tons, 24 vein quartz mines, proven ore reserves of 40.37 million tons; quartz sand mines At 63 locations, the proven ore reserves were 108.73 million tons.
In addition to the annual consumption of ore reserves of nearly 100 million tons, Yunnan Kunming Baimei Village quartz sandstone mine (large), Zhejiang Hangzhou Fanwan quartz sandstone mine (medium), Shanxi Wenxi Wenjiapo vein quartz mine (very small scale) 3 closed outside the pit There are 189 mineral deposits of glass siliceous materials in the country, according to the National Mineral Reserves Committee “Geological Exploration Specifications for Glass Silica Raw Material Deposits (Trial)â€, among which 127 large ore deposits with an ore reserve of more than 2 million tons, 2 to 1 million There are 23 medium-sized mines, 25 small mines of 100-200,000 tons, and 14 small scales of less than 200,000 tons. The total reserves of B+C+D ore are 390.83 million tons. Including 68 quartz sandstone mines (49 large, 10 medium, 6 small, 3 very small), retaining ore reserves of 57.98 million tons (accounting for 15% of total reserves); quartz rock mines 35 (25 large, medium 5, small 5), retaining ore reserves of 2,240,780 tons (accounting for 57% of the total retained ore reserves); 23 vein quartz mines (large 5, medium 3, small 5, 10 small scales), holding ore reserves of 38.4 million tons (accounting for 1% of total retained ore reserves); 63 quartz sand mines (large 48, medium 5, small 9 and very small scale) ), holding ore reserves of 1,409.87 million tons (accounting for 27% of the total retained ore reserves). [next]
The reserves are widely distributed in 27 provinces, municipalities and autonomous regions. The proportion of retained ore reserves and total retained ore reserves is as follows: Qinghai Province, 1.65 billion tons, accounting for 42%; Hainan, Liaoning, Shandong, Shaanxi, Guangdong, Jiangxi, 6 provinces each ranged from 4.2 to 110 million tons, accounting for 38%; Sichuan, Inner Mongolia, Jiangsu, Zhejiang, Hunan, Henan, and 6 provinces and autonomous regions each accounted for 0.9 to 0.6 billion tons, accounting for 10%; Hebei, Guizhou, Gansu, and Shanxi Jilin, Hubei, Heilongjiang, Xinjiang, Ningxia, Yunnan, Beijing, Guangxi, Anhui, 13 provinces, municipalities and autonomous regions each have 0.5 to 0.1 billion tons, accounting for 10%.
There are 64 places (48 large, medium 6, 8 small, and very small) that have been used in the mines. The total reserves of ore are 703.2 million tons, accounting for 18% of the total ore reserves, mainly distributed. Quartz sandstone mines in Jiangsu, Zhejiang, Hunan, etc., quartzite mines in Shaanxi, Liaoning, etc., quartz sand mines in Hainan, Inner Mongolia, Jilin, Fujian, etc.; due to ore quality, processing and mineral processing , transportation and are currently banned For mining reasons, there are 25 mineral deposits (17 large, medium 3, small 2, and very small), which have a total ore reserve of 444.6 million tons, accounting for the total retained ore reserves. 11% are mainly quartz sand mines distributed in Hainan, Shandong and other places, and quartzite mines in Liaoning and Gansu; 100 mineral deposits for large-scale use or further work (large 62, medium 16 and small) 13 places and 9 small scales have a total ore reserve of 276.13 million tons, accounting for 71% of the total retained ore reserves. Among them, 2 quartzite deposits in Datong County, Qinghai Province, have D-class ore reserves of nearly 1.6 billion tons. For further work, the rest are mainly distributed
China's glass siliceous raw material mine has a deep geological work. Among the 192 mineral deposits with proven reserves, 63 (30%) were surveyed, 81 (42%) were investigated in detail, and 48 (25%) were surveyed. . More than 80% of the minerals that have been utilized and more than 70% of the minerals available for near-term use have been explored or scrutinized. Except for Qinghai Province, the B+C reserves in the total reserves of other places account for nearly half, and the majority of the used mineral resources can reach 60% to 80%.
In general, China's glass siliceous raw materials reserves have sufficient reserves, and the total amount of resources can meet the demand for glass industry production in the period before and after 2010. However, there are imbalances in the reserves and utilization rates. Nearly half of the retained reserves are concentrated in Qinghai Province, and the utilization rate is only 2%. There are also six or seven provinces with reserves that are not or basically not used, and some provinces have their own reserves. The reserves can only meet the demand up to around 2010; more than 58% of the retained reserves are quartzite and vein quartzites that are difficult to crush and process, and are prone to excessive superfine powder, iron content in quartz sandstone and quartz sand ore. Generally, the mines with high quality and large quantity for building high-quality flat glass raw material bases are still rare.
