High purity zinc is essential in modern manufacturing thanks to its superior chemical stability, corrosion resistance, and electrical conductivity. As a reliable supplier, Stavian Industrial Metal provides high purity zinc refined to international standards, ensuring consistent performance in galvanizing, die casting, battery production, and chemical applications. With advanced processing technology and strict quality control, we deliver sustainable and high-quality zinc solutions tailored to global industrial demands.
As Stavian Industrial Metal, we emphasize that high purity zinc represents one of the most refined and reliable forms of zinc available for industrial use. Defined by a minimum purity level of 99.99% or higher, high purity zinc contains only trace amounts of lead, iron, cadmium, and copper. This exceptional chemical purity enhances its corrosion resistance, electrochemical behavior, and mechanical performance. It is widely used in galvanizing, die casting, and advanced chemical processes where precision and durability are crucial.
High purity zinc features a bright metallic luster, excellent ductility, and a relatively low melting point of 419.5°C. These characteristics make it suitable for forming, coating, and alloying operations across multiple industries. The metal’s high conductivity and stability under extreme conditions ensure consistent results, particularly in applications that require uniform coating or electrical performance. Moreover, reduced impurity levels mean less residue formation during melting and improved surface finish in the final product.
From a chemical perspective, zinc is an amphoteric metal—reacting with both acids and alkalis—which allows for diverse industrial uses. When refined to high purity, it forms an even and stable oxide layer that protects underlying materials from corrosion. This property makes it indispensable in industries ranging from construction to renewable energy.
The production of high purity zinc begins with zinc ore concentrates, primarily composed of zinc sulfide (ZnS) minerals such as sphalerite. At Stavian Industrial Metal, we ensure that only high-quality raw materials are used, sourced responsibly from trusted mines with transparent environmental and ethical practices. After mining, the ore is crushed, ground, and roasted to convert zinc sulfide into zinc oxide (ZnO). During this roasting process, impurities like sulfur are released as gases and separated.
Once roasted, the zinc oxide undergoes an acid leaching process using sulfuric acid to produce a zinc sulfate (ZnSO₄) solution. This solution contains dissolved zinc along with small amounts of unwanted metals. Purification involves the controlled addition of reagents such as zinc dust to precipitate impurities including copper, cadmium, cobalt, and iron. Maintaining strict control over temperature and pH ensures that only the purest zinc remains in the solution.
Electrolysis is the most critical step in producing high purity zinc. The purified zinc sulfate solution is transferred to electrolytic cells equipped with aluminum cathodes and lead-silver alloy anodes. When electrical current is applied, zinc ions are reduced and deposited onto the cathodes as a thin metallic layer. After several days of controlled operation, the zinc sheets are stripped from the cathodes, melted, and cast into ingots.
This electrolytic refining process yields zinc with purity levels exceeding 99.99%, often referred to as Special High Grade (SHG) or High Purity Zinc depending on the specification. The entire process is carefully monitored to ensure consistency in chemical composition, mechanical properties, and appearance.
At Stavian Industrial Metal, we apply advanced quality control systems to guarantee that every batch of high purity zinc meets international standards such as ASTM B6 and ISO 752. Using spectrometric analysis and precision instrumentation, we verify purity levels and confirm the absence of unwanted elements.
