Gold Refining Test Kit Stannous Chloride Gold Precipitant SMB Scrap Metals

Gold Refining Test Kit for Effective Gold Recovery

Verify dissolved gold in your refining solution and recover it with confidence using this Gold Refining Verification Kit. This bundle includes two essential chemicals used during the final stages of the gold refining process: stannous chloride for testing and sodium metabisulfite (SMB) for gold precipitation.

This kit is designed for refiners working with aqua regia gold refining, scrap gold recovery, and electronic waste refining, where confirming dissolved gold before precipitation is critical.

What’s Included

JSP 1/2 oz Stannous Chloride Gold Testing Solution

Stannous chloride is used by refiners to test aqua regia and gold chloride solutions for the presence of dissolved gold. A small drop of solution is tested to confirm gold is present before moving to the precipitation stage.

1 lb Sodium Metabisulfite (SMB) – GTE Gold Precipitant

Sodium Metabisulfite is one of the most commonly used chemicals for precipitating gold from aqua regia solutions. When added to a prepared refining solution, SMB releases sulfur dioxide which selectively causes dissolved gold to fall out of solution as fine gold powder.

How This Kit Is Used

During the gold refining process:

Scrap gold is dissolved into solution using aqua regia.

Stannous chloride is used to confirm the presence of dissolved gold in the solution.

Once confirmed, sodium metabisulfite (SMB) is added to precipitate the gold from solution.

The gold settles as a fine powder which can be filtered, washed, dried, and melted.

This process is widely used for refining gold from:

• scrap jewelry

• gold-plated electronics

• e-waste materials

• gold alloys and scrap metals

Ideal For

• Aqua regia gold refining

• Scrap gold recovery

• E-waste gold refining

• Precious metal recyclers

• Hobbyist and professional refiners

Additional Information

• Fresh refining chemicals

• Used in standard aqua regia refining methods

• Instructions included with general guidance on the testing and precipitation process

Precision and Efficiency in Gold Refining

The Gold Refining Test Kit provides a reliable and efficient solution for precise gold recovery. Designed specifically for refining gold from SMB scrap metals, this kit uses stannous chloride as the primary gold precipitant. It allows metallurgists, jewelers, and refiners to accurately test and recover gold in a controlled and straightforward process. The kit combines simplicity with precision, making it suitable for both small-scale and professional operations seeking to maximize their gold yield without unnecessary chemical waste or complexity.

How Stannous Chloride Enhances the Gold Precipitation Process

Stannous chloride is an essential chemical in the gold refining process, playing a key role as a gold precipitant. When mixed with an appropriate solution, it effectively reduces dissolved gold ions back into solid gold particles, allowing for easy separation and recovery. This chemical reacts efficiently with gold-bearing solutions from SMB scrap metals, enabling refiners to achieve high purity and recovery rates. The Gold Refining Test Kit includes precisely measured stannous chloride to optimize the precipitation process, enhancing the quality and consistency of the finished product.

Comprehensive Kit Designed for Scrap Metal Applications

This Gold Refining Test Kit is tailored for scrap metal applications, particularly focusing on SMB (Small and Medium-sized Businesses) scrap metals. It includes all necessary reagents and instructions to handle a variety of gold-bearing materials, ensuring adaptability and effective refining outcomes. The kit supports sustainable metal recycling by enabling users to extract gold from scrap metals with minimal environmental impact. Its compact design and easy-to-follow procedures make it an essential tool for anyone involved in precious metals recovery from scrap sources.
