Gold Refining Test Kit Stannous Chloride Gold Precipitant SMB Scrap Metals

Comprehensive Guide to the Gold Refining Test Kit

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

What Is the Gold Refining Test Kit?

The Gold Refining Test Kit is an essential tool designed for professional jewelers, metal refiners, and hobbyists who need accurate and reliable testing of gold purity. By utilizing Stannous Chloride as the core gold precipitant, this kit effectively separates gold from SMB scrap metals. It provides a quick and efficient method for determining the gold content in various samples, enabling users to make informed refining decisions. Easy to use and portable, this test kit simplifies the gold refining process without compromising on precision.

Key Features and Benefits

This Gold Refining Test Kit includes high-purity Stannous Chloride, which acts as a powerful precipitant for recovering gold particles from solutions. Ideal for scrap metal processing, the kit ensures minimal loss of gold during testing. It is formulated to work efficiently even with complex metal mixtures found in SMB (Small to Medium-sized Business) scrap. The kit is user-friendly, safe, and reduces the time required for manual testing, making gold refinement more accessible and cost-effective for both large-scale and small-scale operations.

How to Use the Gold Refining Test Kit Effectively

Using the Gold Refining Test Kit involves dissolving the gold-bearing scrap metal in an appropriate solution, then adding the Stannous Chloride precipitant to recover gold. The process allows clear observation of the gold precipitation from SMB scrap metals, ensuring verified purity levels. Instructions included with the kit guide users step-by-step through preparation, testing, and recovery stages. Proper safety measures and disposal methods are emphasized to guarantee both effective results and user safety. This systematic approach ensures reliable, repeatable testing results and optimal gold recovery.
