GTE Gold Recovery Kit – 2 lb Gold Precipitant (SMB) + 1 lb Urea for Aqua Regia Refining

Comprehensive Gold Precipitation Kit for Aqua Regia Refining

Take control of the final stage of gold refining with the GTE Gold Recovery Kit, built for consistent, reliable precipitation when working with aqua regia solutions.

This kit combines two essential chemicals used in sequence during gold recovery, giving you a complete setup for pulling dissolved gold out of solution cleanly and efficiently.

Whether you’re refining scrap jewelry, recovering gold from electronics, or processing other gold-bearing materials, this bundle is designed for repeat use and higher-volume work.

What’s Included

2 lb GTE Gold Precipitant (Sodium Metabisulfite – SMB)
A proven and widely used precipitant for gold recovery. When added to a properly prepared solution, SMB releases sulfur dioxide, causing dissolved gold to drop out of solution as fine, filterable gold powder.

1 lb Urea (Aqua Regia Neutralizer)
Used to neutralize excess nitric acid before precipitation. Proper neutralization is critical for efficient gold recovery and helps ensure your precipitant performs as expected.

How It Fits Into the Process

1. Gold is dissolved using aqua regia
2. Urea is added to neutralize excess nitric acid
3. SMB is introduced to precipitate the gold
4. Gold settles as a fine powder for filtering, washing, and melting

Why This Kit

• Sized for ongoing refining work (not just small test batches)
• Balanced ratio of neutralizer and precipitant
• Designed to work seamlessly within standard aqua regia workflows
• Trusted process used by both beginners and experienced refiners

Ideal For

• Scrap gold refining
• E-waste gold recovery
• Precious metal recycling
• Hobbyist and professional refiners

Important Notes

• For use in gold refining processes only
• Always follow proper safety procedures when handling chemicals
• Ensure full nitric neutralization before precipitation for best results

Effective Gold Recovery with SMB Gold Precipitant

The GTE Gold Recovery Kit offers a premium Gold Precipitation Kit designed to maximize gold recovery efficiency. Central to this kit is 2 lb of Sodium Metabisulfite (SMB), a proven gold precipitant widely used in aqua regia refining. SMB causes gold ions dissolved in aqua regia to precipitate out as metallic gold, simplifying the recovery process. Its high purity ensures rapid and complete precipitation, which improves yield while minimizing chemical waste. This makes the kit an essential tool for hobbyists and professionals alike aiming for optimal gold extraction.

Supplemental Urea to Optimize Refining Process

The kit also includes 1 lb of Urea, an important component that enhances the Aqua Regia refining process. Urea is used to neutralize excess nitric acid, stabilizing the solution before precipitation takes place. By carefully controlling the chemical environment, the Urea helps prevent the loss of fine gold particles and reduces the formation of unwanted byproducts. This complementary chemical increases the overall safety and efficiency of gold precipitation, ensuring a clean, simplified refining experience.

Complete and Convenient Package for Refining Needs

Designed for convenience, the GTE Gold Recovery Kit combines essential chemicals in a single package, making it easy to procure everything necessary for gold precipitation. The pre-measured 2 lb SMB and 1 lb Urea quantities meet the common demands of aqua regia refining tasks without unnecessary excess. Whether for small-scale refining or larger operations, this kit delivers reliability and quality. With detailed usage guidelines and expert-approved components, it is suitable for users of all skill levels seeking a dependable gold precipitation solution.
