As an advanced metal purification technology, electrolytic extraction of high-purity antimony has shown significant advantages in the field of hydrometallurgy. This process uses electrochemical reactions to dissolve the crude antimony anode in the electrolyte solution and precipitate pure antimony at the cathode, achieving efficient separation of impurities and antimony.

Its core advantage lies in the ability to prepare high-purity products. Although traditional methods can purify antimony, it is difficult to achieve semiconductor-grade purity. The electrolytic method can prepare ultra-pure antimony with a purity of 99.99% by optimizing the electrolyte composition and electrolysis conditions, which meets the stringent requirements for epitaxial growth of semiconductor materials such as gallium arsenide. This high-purity product provides key raw material support for high-end fields such as new energy and electronic information.

The economic and environmental performance of the electrolytic process is also outstanding. The new centrifugal extractor is used in conjunction with electrolysis technology to remove impurities step by step through a multi-stage extraction system, significantly reducing solvent consumption and energy consumption. The equipment adopts a modular design, supports single-stage or multi-stage series countercurrent operation, has a large processing capacity and a small footprint, and the unit production cost is reduced by 90% compared with traditional methods. In addition, the electrolyte can be recycled, the waste liquid treatment meets environmental protection standards, high-temperature roasting is not required throughout the process, and carbon emissions are greatly reduced.

In terms of complex material processing, the electrolytic method shows strong adaptability. By adjusting the electrolyte concentration, pH value and current density, the target elements in the antimony, lead and zinc polymetallic symbiotic ore can be effectively separated to achieve comprehensive resource utilization. For example, in a project in Yunnan, the antimony recovery rate reached 85%, and the lead and zinc direct recovery rates increased to 90% and 88% respectively, and the comprehensive economic benefits were significantly improved.

The electrolytic extraction of high-purity antimony process is gradually becoming a core technology in the field of hydrometallurgy with its high-purity preparation capability, economic and environmental characteristics and complex material processing advantages, providing important technical support for promoting the transformation of the antimony industry to high-end and green.
