It is understood that China has achieved many important achievements and understandings in diamond prospecting in the 1950s and 1980s. However, after the mid-1990s, diamond prospecting turned into a downturn and tended to stop. Since the beginning of this century, with the resurgence of the world diamond prospecting boom, coupled with the new demand for diamond resources in China's strategic emerging industry development, diamond prospecting has been put on the agenda, and the prospecting breakthrough strategic action has also listed diamond prospecting as an important emerging Industrial minerals. Since 2005, the China Geological Survey has conducted secondary development and constituency research on diamond geological data, and has gradually initiated diamond survey evaluation in key areas of the Yangtze Platform and the Tanlu fault zone. In 2007, the research on the exploration direction and abnormality of the diamond prospecting in the Yangtze platform was carried out. From 2010 to 2013, it was successively carried out in Liaoning Wafangdian, Guizhou Zhenyuanping, Hunan Changde-Xiangtong, Shandong Mengyin County Taohuayu-Shuangquanshan. The diamond survey and evaluation, and the deployment of the 1:25000 aeromagnetic survey of the diamond primary mine in the adjacent area of ​​Xiangyu. In addition, research on diamond mineralization conditions and strategic selection of the North China Block and Yangtze Platform has been carried out, and data and technical preparations have been carried out for the new round of diamond prospecting.
In recent years, new progress has been made in diamond prospecting: Liaoning Wafangdian and Shandong Changma deep have added more resources. Three diamond-bearing rock pipes were discovered in the railings of Anhui Suzhou, and the diamond cues were found in the artificial heavy sand survey of Taojiangjiang Shiqiao, Hunan. These results enhance the confidence of diamond prospecting. On the next step of how to promote diamond prospecting, Li Jinfa said that the China Geological Survey will give full play to the role of public welfare and make overall arrangements, deepen the study of strategic constituencies, carry out prospective investigations, strengthen key evaluations, and strengthen theoretical methods and technical support. Focus on promoting diamond prospecting breakthroughs. It is understood that the China Geological Survey will focus on the North China Block Rift Fault Zone and the Yangtze Platform Xuefeng Ancient Land, taking into account other areas with diamond prospecting clues such as the Ordos ancient land and the Tarim platform, and coordinate the deployment of diamond prospects. In Liaoning, Shandong, Anhui, Hunan, Guizhou, Guangxi and other provinces with high working level and many diamond prospecting clues, it is preferred to find a prospecting target area that is expected to break through in the near future, carry out key evaluations, increase engineering verification efforts, and strive to strengthen Achieving demonstration effects and leading a new round of diamond prospecting in the country.
The meeting was jointly organized by the China Geological Survey and the Hunan Provincial Department of Land and Resources. At the meeting, experts discussed the metallogenic conditions, metallogenic structures and prospecting methods of diamonds. Experts believe that the Yangtze platform has the ore-forming geological conditions and good prospecting prospects for the formation of diamond primary ore, but to achieve the breakthrough of the Yangtze platform diamond prospecting, it is necessary to use new thinking, new perspectives, and pay attention to kimberlite diamonds. For prospecting, it is necessary to pay attention to the prospecting of potassium-magnesium lamprophyre type diamonds. It is necessary to further strengthen the development of secondary data, strengthen the study of geological evolution and metallogenic conditions, and pay attention to the collection and observation of samples, and find the prospecting clues.
Product Introduction
Silicon Carbide Sand is a part of Silicon Carbide . It is most widely used in the modern C, N, B, and other non oxide high technical refractory raw materials. Silicon carbide hardness is very high, the Mohs hardness is a magnitude 9.5, the second only to the world's most hard diamond (10). It with excellent thermal conductivity, is a semiconductor, high temperature resistant to oxidation. Low grade silicon carbide (containing about 85 per cent of the SiC) is an excellent deoxidizing agent, it can accelerate the speed of steel-making, and easy to control the chemical composition, improving steel quality.
The silicon carbide has Green Silicon Carbide and Black Silicon Carbide. Black Silicon carbide used for semiconductor, lightning rod, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutch, diesel particulate filter, filament pyrometer, ceramic film, cutting tools, heating elements , Nuclear fuel, jewelry, steel, protective gear, catalyst support and other fields.
