Gold Refining Kit – Sodium Metabisulfite (SMB) Gold Precipitant + Borax Flux
Complete the final stages of the gold refining process with this Gold Recovery & Melting Kit. This bundle includes the essential materials used to recover gold from solution and prepare it for melting.
Designed for refiners working with scrap gold, jewelry, electronic waste, and precious metal recovery, this kit combines a gold precipitant with traditional melting flux used by refiners and jewelers.
What’s Included
1 lb Sodium Metabisulfite (SMB) – GTE Gold Precipitant
Sodium Metabisulfite is widely used during gold refining to precipitate dissolved gold from solution. When added to prepared refining solutions, it causes dissolved gold to fall out of solution as fine gold powder.
1 lb Borax Flux – GTE Gold Melting Flux
Borax is commonly used during the melting stage of refining. It helps remove impurities and assists in forming clean, smooth gold melts when refining recovered gold powder.
How It Works
In many gold refining workflows:
Gold is dissolved into solution using refining methods.
Sodium Metabisulfite (SMB) is added to recover the gold from solution.
The recovered gold powder is filtered and dried.
Borax flux is used during the melting process to help produce clean refined gold.
