Chapman Flux Powder for Smelting & Assaying Gold Silver Electronics Rock Ore Blacksands

Professional-Grade Flux for Maximum Precious Metal Recovery

Chapman Flux is the trusted choice for assayers, refiners, and precious metal recovery professionals who demand consistent, reliable results. This specially formulated flux powder ensures optimal separation and maximum yield when processing gold, silver, and other precious metals from ore, black sands, electronic scrap, and concentrates.

Key Benefits

• Maximizes Metal Recovery: Engineered to lower melting points and promote complete fusion, ensuring you capture every trace of precious metal from your material
• Clean Separation: Creates a fluid slag that cleanly separates base metals and impurities from your gold and silver, resulting in purer buttons and more accurate assays
• Versatile Applications: Works effectively with rock ore, black sands, electronic waste, jewelry scrap, and mining concentrates
• Consistent Results: Precisely balanced formula delivers repeatable outcomes for both fire assay and smelting operations
• Professional Quality: Trusted by commercial refineries, assay labs, and serious prospectors for critical precious metal analysis

Ideal For

• Fire assay cupellation procedures
• Smelting gold and silver from ore and concentrates
• Electronic waste precious metal recovery
• Black sand processing
• Jewelry scrap refining
• Mining sample analysis

How It Works

Chapman Flux combines with your charge material during heating to create a molten slag that absorbs impurities and base metals. The flux lowers the melting point of the mixture, promotes thorough mixing, and allows precious metals to collect at the bottom while waste materials float to the top for easy removal.

Usage Guidelines

Mix Chapman Flux with your material according to your specific application and charge weight. Typical ratios range from 2:1 to 4:1 flux-to-ore, depending on material composition. Always use in well-ventilated areas and follow proper safety protocols for high-temperature operations.

Made in USA - Quality you can trust for accurate precious metal analysis and recovery.
