Key Findings in This Report

• • The revised standard YS/T 1093-2024 expands the classification to six typical zinc-bearing materials, including low-grade complex materials with zinc content as low as 5%-15%, broadening the resource base and mitigating structural shortages. • • Stringent limits on harmful elements (fluorine, chlorine, lead, arsenic) are enforced, reducing environmental risks and enabling compliance with stricter emission regulations. • • New operational indicators, such as moisture control and appearance evaluation, improve standard operability and facilitate quality assurance in industrial practice. • • The standard's systematic alignment with EU standards enhances international competitiveness and supports cross-border trade of recycled zinc materials.
