Tantalum (Ta), niobium (Nb) are all high melting point (2996 deg.] C tantalum, niobium 2468 deg.] C), a high boiling point (5427 deg.] C tantalum, niobium 5127 deg.] C) a noble metal, like steel appearance, shiny gray, dark gray powder, having Inhalation, corrosion resistance, superconductivity, unipolar conductivity and high strength at high temperatures. Therefore, the current high-tech industries related to the application of new materials, tantalum and niobium including electronics, fine ceramics and precision glass industry; electro-acoustic optical devices; carbide, aerospace and industrial electronic energy; Biomedical Engineering; superconducting industry; special steel industry. é’½ and é“Œ have a very important position in the electronics industry, chemical industry, special alloys, vacuum technology and cutting-edge technology. Electrolytic capacitors made of base metals in the electronics industry have outstanding characteristics such as large capacitance, small leakage current, good stability, high reliability, good pressure resistance, long life and small volume. It is widely used in electronic circuits of national defense, aviation, aerospace, electronic computers, high-end civil appliances and various electronic instruments. In the metallurgical industry, niobium is mainly used as an additive for the production of high-strength alloy steels, to improve the properties of various alloys and to make superhard tools. Recently, the process of industrialization and the depreciation of the US dollar around the world have accelerated the sharp rise in the prices of metals and non-metals, and the market demand for rare metals has further increased. The research and development and production of high-tech products such as é’½, é“Œ, etc. have entered a new period of growth. Ningxia Oriental Nonferrous Metals Group, the first national high-tech enterprise recognized by the Ministry of Science and Technology, is the first in the same industry in the country to be accepted as a member of the International Research and Development Center (TIC). Twenty-three varieties are high-tech products in the field of new materials. Tantalum powder and silk fiber account for 20% and 45% of the world's market share respectively. They are also extremely important in China's national defense, nuclear energy, aerospace, electronics, metallurgy and chemical industries. The new material supply base represents a new turning point in China's rare metal industry. 钽铌Market warming application growth In recent years, with the demand for computers, digital cameras, mobile phones, and in-vehicle electronic systems, the demand for sputum is gradually coming out of the trough. The price of antimony concentrate has also returned to normal levels. In recent years, the total demand for plutonium in the world has been around 2,000 tons, while the demand for plutonium is more than 20,000 tons. The main use of plutonium is tantalum powder for capacitors and its silk, which accounts for more than half of the total consumption; the main use of plutonium is made of steel additive, the amount of the total consumption of nearly ninety percent; in 2000 was in the peak of tantalum consumption, the total amount of tantalum reached a record 2235 tons in 2001 quickly fell under 1562 tons, to In 2004, its output increased steadily to nearly 2,000 tons; the demand for antimony has been relatively stable. China's resource advantage is obvious Some extra large or large antimony mines in China: Characteristics: The size of the antimony deposit is small, the grade of ore is low, the size of the inlay is fine and scattered, and the multi-metal is associated with it, which makes it difficult to collect, difficult to divide, difficult to select, and has low recovery rate; the occurrence state is poor, and there are few large-scale exposed mining mines. There is no independent mine in China, and it is often associated with rare earths and earthworms. Reserves: The minimum industrial grade index calculated by China's reserves for antimony deposits is: (Ta, Nb) 205 0.016-0.028%. The grades of most antimony deposits in China are close to or slightly higher than the minimum industrial grade. There are almost no 205% grades of Ta205, and there are only a few carbonate rock deposits with Nb205 grade over 0.1%. The Nb205 grades of other types of deposits are around 0.02%. 钽铌Reservoir data show that China's Ta (Ta205) reserves and basic reserves are still very large in quantity, but there is almost no more than 0.02% of Ta205 grade in China's é’½ resources. Obviously, the “reserves†changed with such low grades The reserves calculated by foreign high grades are difficult to compare. The same is true of é“Œ. 钽铌 smelting, processing technology continues to innovate Hydrometallurgy Slurry extraction; pyrolysis, low acid extraction; off-line analysis, on-line analysis and computer monitoring; cold crystallization of potassium fluoroantimonate; continuous spray precipitation to produce low-fluorine Ta205, Nb205; peroxidation precipitation to produce high purity Ta205, Nb205; Flux mixing - clarification extraction tank and combined extraction equipment; using internationally advanced potassium fluoroantimonate vacuum rotary drying equipment and far infrared continuous drying equipment.

In addition to Ningxia Nonferrous Metals Smelter, Zhuzhou Cemented Carbide Co., Ltd., Jiujiang Nonferrous Metals Smelter, Guangxi Limu Nonferrous Metals Industry Co., Ltd. and Guangdong Conghuayu Smelter, these five old backbone enterprises continue to invest and upgrade, Guangdong Doro Mountain Lanzhou Gems , Guangdong Fogang Jiate, Hengyang Jinxin Laifu and other companies took the opportunity to become a rising star of the industry. Even after the market turmoil in 2000-2001, there are still 10 companies in Guangdong, Jiangxi and other provinces joining the industry, and some investors are ready to enter the industry. In 2005, there were more than 40 manufacturers of plutonium in China. Initially, the current production of enamel products in China is about 800 tons of metal bismuth, accounting for one-third of the world's total output. The production capacity of K2TaF7 is over 2,000 tons, accounting for more than 50% of the world's total demand. It can be said that China has become the world. A big industrial country. Thoughts on China's Industrial Industry The development of the smelting and processing industry is mainly constrained by the two factors of the utilization of é’½ resources and the application of é’½ products. At present, the current situation of é’½ resources and the wide application of é’½ products make the development of smelting and smelting industry in a contradiction between supply and demand. Since the 1990s, raw materials have been in short supply, and 70% of the world's antimony concentrates are still insufficient in this field, resulting in a 600% increase in niobium minerals. China's antimony deposits are widely distributed, but most of the antimony ore grades are low and the utilization rate is low. In the 1990s, the development speed of China's plutonium industry was extremely rapid, and the problem of insufficient supply of raw materials was gradually exposed. At present, China's 钽铌 钽铌 is a non-governmental organization that organizes the overall interests of the industry and plays an active role in protecting the overall interests of the industry. In today's booming development of our country, it is necessary to establish an association in a timely manner to coordinate the relationship between enterprises, safeguard the overall interests of the industry, and assist the government in formulating industry development plans. Encourage collaboration between companies. Especially after the market volatility in 2000-2001, we should encourage the establishment of long-term and mutually beneficial supply and demand relations between raw material enterprises and smelting enterprises, and share the same glory and shame, and enhance the overall risk resistance. Encourage enterprises to go abroad and establish long-term and stable supply and demand relations with foreign companies, and actively and steadily develop foreign resources. It is recommended that the relevant state departments formulate policies, increase support for the development of new technologies and new products, support the export of high-tech products, and establish a new product development base and export base combining production, study and research.
