Zinc waste and scrap

Product Detail

Zinc waste and scrap

Zinc waste and scrap consist of recycled or discarded zinc materials, typically sourced from manufacturing, construction, galvanizing, and die-casting processes. This category includes various forms of zinc residues, such as zinc dross, skimmings, ashes, and old scrap materials. The quality and composition of zinc scrap depend on the source and processing method.

Specifications:

Specifications vary depending on the type and intended use of the scrap. Below are general parameters:

Purity: 85% – 99% Zn (varies by scrap type)
Impurities:
- Lead (Pb): ≤ 1%
- Iron (Fe): ≤ 0.5%
- Cadmium (Cd): ≤ 0.1%
- Copper (Cu): ≤ 0.5%
Common Types of Zinc Scrap:
- Zinc Dross: Residue from the galvanizing process, containing high zinc content
- Zinc Ash: By-product from melting zinc, containing metallic and oxidized zinc
- Zinc Skimmings: Surface waste from molten zinc baths
- Old Zinc Scrap: Used or discarded zinc materials (e.g., sheets, pipes, die-castings)
Form: Sheets, dross, ash, skimmings, mixed metal scrap
Moisture Content: ≤ 2% (varies based on type)
Packaging: Loose, in bales, or in drums
