| Abstract: |
| Antimony is classified as a strategically advantageous metal in China, primarily sourced from the smelting and extraction of stibnite ore. Its compounds play an indispensable role in the production of flame retardants, alloy manufacturing, and photovoltaic glass. Currently, the predominant method for producing metallic antimony in China involves the "Blast furnace volatilization - Reverberatory furnace reduction" process. This process is characterized by a high coke rate and low oxygen concentration during smelting, resulting in the emission of large quantities of low-concentration SO?, thereby causing severe environmental pollution. In the context of China""s implementation of the "Dual carbon" strategic goals and comprehensive ecological environment management, achieving low-carbon and environmentally clean antimony smelting has become a critical issue for the sustainable development of the antimony smelting industry. The latest advancements in the development of green processes for antimony smelting were reviewed, the current technological status and research progress in stibnite ore smelting was comprehensively summarized, and the features of the new molten salt electrolysis technology for desulfurization and antimony production were highlighted. The aim is to provide recommendations and guidance for the green and sustainable development of the antimony smelting industry. |
