| Mapping the Evolution of the Global Antimony Raw Materials Trade Pattern |
| The global supply-demand pattern for antimony-containing materials is changing as China’s mine production declines and global demand for antimony-containing materials increases in new energy sectors. An analysis of the global antimony raw materials trade pattern can help countries build their own resilient supply chains of antimony raw materials. Using material flow and complex network analysis methods, this study quantitatively depicts the global trade pattern of four types of antimony raw materials (antimony ore, antimony metal, primary processed materials of antimony, and secondary antimony) from 2002 to 2020. Additionally, the evolutionary characteristics of the global antimony raw materials trade pattern and national status are analyzed. Primary processed materials containing antimony were found to be the most important type of commodity, with trade volumes accounting for more than half of the global trade volumes of antimony raw materials. China and the United States were found to be the two countries with the most comprehensive trade status, while India, the EU, and South Korea were the countries (regions) with the fastest rise in comprehensive trade status. The EU’s import sources of antimony showed an obvious diversification trend, which significantly reduced its import dependence on China, indicating that the EU’s import strategy of critical raw materials has achieved remarkable results in recent years. China’s absolute dominance in the global supply of antimony raw materials is declining with the development of a more diversified pattern of global antimony raw materials trade. |
