In the comprehensive process of producing high-purity antimony trioxide powder from antimony ore, electrolytic refining serves as a pivotal purification stage that bridges upstream and downstream operations. The electrolytic antimony equipment provided by our company empowers clients to efficiently produce high-purity cathode antimony while simultaneously recovering valuable metals, making it an ideal choice for enhancing both product quality and economic returns.

I. Efficient Purification: Ensuring High-Purity Antimony Quality

The equipment utilizes crude antimony anode plates as feedstock and operates within a specific electrolyte system under an applied electric current. Antimony selectively deposits at the cathode, effectively eliminating impurities such as arsenic, lead, and iron. The resulting cathode antimony, following subsequent melting and casting, can be directly utilized in the preparation of electronic-grade and flame-retardant-grade Sb₂O₃ powders.

II. Comprehensive Recovery of Valuable Metals

During the electrolysis process, precious metals—such as silver and gold—remain undissolved and accumulate in the form of anode slime. This anode slime can be further processed to recover these valuable elements, thereby opening up additional revenue streams for the enterprise and facilitating the recycling of resources.

III. Precise and Controllable Process Parameters

Equipped with an advanced electrical control system, the unit allows for the real-time adjustment of current, voltage, electrolyte temperature, and circulation velocity. This ensures high current efficiency and stable deposition quality, making the system highly suitable for large-scale, continuous production operations.

IV. Seamless Integration with Upstream and Downstream Processes

Crude antimony can be directly cast into standardized anode plates for immediate use. The cathode antimony produced features a regular, uniform morphology, facilitating subsequent remelting and high-temperature evaporative oxidation processes; this minimizes the need for intermediate pretreatment steps and optimizes overall production line efficiency.

V. Energy Efficiency, Safety, and Environmental Protection

The system boasts high current efficiency, while its corrosion-resistant structural design ensures an extended service life. Enclosed operational protocols minimize the emission of acid mists; furthermore, the system can be integrated with waste liquid treatment units, features centralized recovery of anode slime, and generates minimal solid waste residues—thereby fully complying with "Green Factory" standards.

Application Scenarios: Production of high-purity antimony ingots, preparation of precursors for flame-retardant-grade Sb₂O₃, recovery of precious metals from antimony-bearing materials, etc.
