The main niobium and tantalum smelters in China are: Ningxia Nonferrous Metal Smelter (Dongfang Nonferrous), Northwest Rare Metal Materials Research Institute, Zhuzhou Cemented Carbide Plant, Jiujiang Nonferrous Metal Smelter, Guangxi Limu Nonferrous Gold Company, Guangdong Conghua Tantalum and Niobium Smelter. Continuous innovation of tantalum-niobium smelting and processing technology, such as: hydrometallurgy-pulp extraction; pyrolysis--low acid extraction; offline analysis-online analysis and computer monitoring; potassium fluorotantalate cold crystallization; continuous jet precipitation production low Fluorine Ta2O5, Nb205 process; peroxide precipitation to produce high-purity Ta205, Nb205, etc.

Niobium and tantalum products mainly include: tantalum powder, niobium powder, tantalum plate, ingot, rod, wire, tube, sheet, etc. According to the statistics of 2006.06, the output of tantalum and niobium metal in my country is: tantalum powder--82t tantalum oxide--25t tantalum carbide-20t tantalum material-5t metal niobium-60t niobium oxide-60t niobium iron--300t niobium material-- 3t Application of tantalum and niobium metal materials The applicable fields of new tantalum and niobium materials include: electronics, precision ceramics and precision glass industries; electroacoustic and optical devices; cemented carbide, aerospace and electronic energy industries; biomedical engineering; superconducting industry; Special steel and other industries. In the electronics industry, tantalum metal can be used to manufacture electrolytic capacitors, which have the outstanding characteristics of large capacitance, small leakage current, good stability, high reliability, good voltage resistance, long life, and small size. In addition, tantalum is also widely used in the electronic circuits of national defense, aviation, aerospace, electronic computers, high-end civil electrical appliances and various electronic instruments. In the metallurgical industry, tantalum and niobium are mainly used as additives for the production of high-strength alloy steel, the improvement of various alloy properties and the production of superhard tools.
