Supported by modern hydrometallurgical equipment, alkaline hydrometallurgical antimony smelting technology can be operated efficiently, providing a strong guarantee for the extraction of pure metallic antimony from high-arsenic antimony ore. This method achieves clean purification of antimony through two core steps: alkaline solution leaching and electrolytic deposition.

In the alkaline hydrometallurgical antimony smelting process, the special leaching equipment fully contacts the mixed solution of sodium sulfide and sodium hydroxide with the antimony concentrate to convert the antimony compound into water-soluble sodium thioantimonite. By precisely controlling the leaching conditions, such as temperature, liquid-solid ratio and reaction time, the impurities such as antimony and arsenic are effectively separated, laying a solid foundation for subsequent purification.

The leached solution enters the purification equipment, and impurities such as arsenic and tin are removed by chemical methods. The purified solution is clear and transparent, providing high-quality raw materials for electrolytic deposition.

Subsequently, in the electrolytic equipment, the purified solution is reduced to metallic antimony on the cathode under the action of direct current, and the antimony ions are deposited into a dense antimony layer. The design and optimization of the electrolytic equipment ensures the high efficiency and stability of the electrolytic process and the high quality of cathode antimony.

The alkaline hydrometallurgical antimony smelting technology has shown broad prospects in the field of antimony metallurgy with its advantages of good selectivity, high metal recovery rate and environmental protection. However, the investment and maintenance costs of equipment are also factors that need to be considered. In order to reduce costs and improve efficiency, we need to continuously optimize equipment design and process parameters.

In short, relying on advanced hydrometallurgical equipment, the alkaline hydrometallurgical antimony smelting technology provides a reliable way to extract pure metallic antimony from high-arsenic antimony ore. In the future, with the continuous upgrading of equipment and continuous optimization of processes, the alkaline hydrometallurgical antimony smelting technology will play a more important role in the antimony metallurgical industry.
