Description

Leach Residues, Zinc-Fume is a secondary raw material derived from the hydrometallurgical processing of zinc-bearing ores or concentrates. This material is of significant commercial value as a strategic source of recoverable metals, primarily zinc, for recycling and reprocessing within the metallurgical industry. It is essential for smelters, metal recovery facilities, and manufacturers of zinc-based chemicals seeking cost-effective and sustainable feedstock.

Application

• Zinc Recovery Feedstock: Primary application as a secondary feed material for zinc smelters (Imperial Smelting Process, Waelz kilns) to recover metallic zinc.
• Ferrite Production: Used in the manufacturing of zinc ferrites for applications in electronics and magnetic materials.
• Zinc Oxide Synthesis: Serves as a precursor in the production of zinc oxide for the rubber, ceramic, and pharmaceutical industries.
• Construction Materials: Incorporated into cement and concrete formulations to impart specific properties or for stabilization.
• Micronutrient Supplement: Processed for use in agricultural products as a source of zinc, an essential plant micronutrient.
• Wastewater Treatment: Utilized in precipitation processes for heavy metal removal in industrial effluent treatment.

Quality Control

Our Leach Residues, Zinc-Fume is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and reliable performance for downstream processes. Each lot is characterized for key metallic content and physical parameters. A comprehensive Certificate of Analysis (COA) detailing zinc, iron, lead, and other trace element assays is provided with every shipment to support your quality assurance and process control requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area. Store away from incompatible materials. For long-term storage, keep containers sealed under dry, inert atmosphere to prevent caking and oxidation.
