Abstract:
Tungsten is an important metal resource, widely used in the industrial production field. Tungsten ore has been listed in the strategic mineral catalog by countries or organizations such as Japan, the European Union, the United States, China, Australia, and others. In recent years, with the increase in the production cost of tungsten concentrate and the increase in the utilization ratio of recycled tungsten, new challenges have been posed to the global supply of tungsten resources. Based on the statistical data related to tungsten resources and the global tungsten resource production data from 2018 to 2022, statistical analysis is conducted on the distribution characteristics of global tungsten ore resources, tungsten ore deposit types and distribution characteristics, and global tungsten ore resource production. The conclusion drawn through research is that China has an advantage in the upstream resource end and the midstream smelting end. In 2022, China’s tungsten reserves account for 54.7% of the global tungsten reserves, tungsten concentrate supply account for about 83.2% of the world’s total, the production of ammonium paratungstate accounts for 74.4% of the world’s total, the production of tungsten powder and tungsten carbide powder accounts for 71%-74% of the world’s total. Combined with the global trade data analysis of tungsten ore and its concentrate trade in the upstream of the tungsten industry chain and smelting products in the middle reaches, the global tungsten consumption countries and regions are relatively concentrated, mainly concentrated in Europe, the United States, Japan and China, etc. These countries and regions account for about 90% of the total global tungsten consumption. China is the world’s largest consumer of tungsten resources. In 2022, the global consumption of tungsten was 108 200 tons, and China’s tungsten consumption was 63 000 tons, accounting for 58.3% of the total global consumption. China mainly imports tungsten concentrate and exports intermediate products; developed countries and regions such as the United States, Europe and Japan import tungsten concentrate, ammonium paratungstate and other products for processing, and export tungsten products with high technical content and high added value. It is recommended to strengthen the exploration of tungsten resources, promote the sustainable development of tungsten resources, and ensure the safety of tungsten resources supply. To promote scientific and technological innovation, improve the utilization efficiency of tungsten resources, promote the development of secondary recycling technology of tungsten resources, reduce production costs and environmental pollution. To optimize the industrial structure, actively participate in the competition and cooperation in the international tungsten market, and improve the added value and international competitiveness of China’s tungsten industry.
