Description

Residues, Precious Metal-Refining CAS NO 124222-18-0 are intermediate materials generated during the recycling and purification processes of precious metals such as gold, silver, platinum, and palladium. These residues are of significant value as they contain recoverable quantities of precious metals, making them a critical feedstock for secondary refining operations. They are essential for companies in the precious metal recycling, electronics scrap recovery, and catalytic converter processing industries seeking to maximize resource efficiency and economic yield from waste streams.

Application

• Secondary Precious Metal Refining: Primary feedstock for smelters and refineries to recover gold, silver, platinum group metals (PGMs).
• Electronics Waste (E-Waste) Processing: Source material for extracting precious metals from printed circuit boards (PCBs), connectors, and chips.
• Catalytic Converter Recycling: Input material for processes designed to reclaim platinum, palladium, and rhodium from spent automotive catalysts.
• Jewelry and Dental Scrap Refining: Used in operations that purify precious metals from manufacturing scraps and end-of-life products.
• Industrial Catalyst Recovery: Feedstock for recovering precious metals from spent catalysts used in chemical and pharmaceutical manufacturing.
• Mine Tailings and Slag Reprocessing: Utilized to extract residual precious metal values from primary mining and processing wastes.

Quality Control

Our precious metal refining residues are sourced and processed under strict protocols to ensure consistent composition and metal content. Each lot is characterized to provide an estimated precious metal grade, which is critical for refining yield calculations. Certificates of Analysis (COA) detailing metal assay results (via fire assay, ICP-OES, or XRF) and physical description are available upon request to support your process planning and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a dry, well-ventilated area at ambient temperature (15-25°C). Keep away from incompatible materials such as strong acids and oxidizers. Due to the variable and potentially reactive nature of these materials, isolate from general chemical storage.
