Chapman’s Flux – Gold Smelting Flux for Black Sands, Ore & Precious Metal Refining

Chapman’s Flux is a professional premixed smelting flux designed for gold prospectors, refiners, and metal casters. This ready-to-use blend helps separate precious metals from black sands, ore concentrates, and scrap metals during the smelting process.

The formula combines borax, soda ash, silica, and manganese to create a powerful flux mixture that promotes impurity separation and improves metal recovery.

Chapman’s Flux is widely used in gold prospecting, refining, and small-scale smelting operations when processing concentrates, scrap jewelry, computer parts, and other precious-metal bearing materials.

Simply add the flux during smelting to help impurities separate from molten metal and produce cleaner pours and better recovery.
