Gold Recovery Kit 1lb Sodium Metabisulfite SMB + 1lb Aqua Regia Urea Gold Scrap Refining
Stock your refining workspace with two GTE chemicals used in gold recovery: urea and sodium metabisulfite (SMB). This two-bag bundle supplies chemicals for specific solution-treatment and precipitation stages of an established gold refining process.
1 lb GTE Gold Precipitant – Sodium Metabisulfite (SMB): Used to precipitate dissolved gold from properly prepared gold chloride solutions, allowing the recovered gold powder to be collected for further processing.
1 lb GTE Urea (aqua regia): Used in certain refining procedures to treat nitrous acid in solution. Urea does not dissolve gold and should not be relied upon to eliminate all excess nitric acid.
Both products are GTE branded and packaged in resealable bags.
The urea bag may be labeled “Aqua Regia.” Its contents are solid urea—not premixed aqua regia, nitric acid, or hydrochloric acid.
This bundle does not dissolve scrap gold on its own and is not a complete refining system. Recovery results depend on the starting material, solution preparation, contaminants, and refining method. No specific yield or final gold purity is guaranteed.
Depending on your established refining procedure, additional supplies may include:
Appropriate refining acids, purchased separately
Chemically compatible vessels and filtration equipment
Gold-testing solution, such as stannous chloride
Suitable protective equipment and a properly equipped chemical workspace with effective fume extraction
Appropriate waste collection and disposal arrangements
For users trained in chemical handling and precious metal refining. Follow the product labels, Safety Data Sheets, and a validated refining procedure. Refining acids and SMB used in acidic solutions can release hazardous gases. Keep chemicals away from children, pets, and incompatible materials.
Includes two chemical bags only. Acids, testing solutions, glassware, filtration equipment, and other refining supplies are sold separately.
