Gold Refining Test Kit Stannous Chloride Gold Precipitant SMB Scrap Metals

Gold Refining Test Kit for Efficient Gold Analysis and Purification

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

Overview of the Gold Refining Test Kit

The Gold Refining Test Kit is an essential tool designed specifically for accurately testing and refining gold in various forms, including SMB scrap metals. This kit leverages the power of stannous chloride as a gold precipitant, ensuring precise and reliable results for professionals and hobbyists alike. Whether you're dealing with raw gold ore, jewelry scrap, or electronic gold-containing materials, this kit simplifies the testing process and improves recovery rates during gold refining.

How Stannous Chloride Enhances Gold Precipitation

Stannous chloride is a key chemical in the Gold Refining Test Kit, acting as an effective gold precipitant. When added to gold-bearing solutions, it facilitates the reduction of dissolved gold ions into solid metallic gold. This process enables refined separation of gold from impurities and other metals commonly found in SMB scrap. The use of stannous chloride not only speeds up precipitation but also contributes to higher purity and better yield in the refinement process.

Applications and Benefits of the Kit in Scrap Metal Refining

This Gold Refining Test Kit is ideal for testing gold content in various scrap metals, including electronics, jewelry remnants, and industrial gold alloys. Its user-friendly setup and clear instructions make it accessible to both experts and beginners in metal refining. By using this test kit, users benefit from accurate gold analysis, cost-effective refining, and improved metal recovery, ensuring that valuable gold is efficiently extracted from complex scrap materials.
