Thiourea 16 oz – Gold Stripping & Precious Metal Refining Chemical

Thiourea is a specialized chemical used in precious metal refining and gold recovery processes. It is commonly used as an alternative gold leaching agent in situations where refiners want to dissolve gold from plated materials or electronic scrap.

Unlike traditional aqua regia refining methods, thiourea solutions can selectively dissolve gold under the right chemical conditions, making it useful for certain recovery applications.

Refiners often use thiourea when processing gold-plated electronics, connectors, pins, and other scrap materials containing thin layers of gold.

How Thiourea Is Used

In most refining processes, thiourea is first dissolved into an acidic solution to create a gold-leaching solution.

The material containing gold, such as gold-plated electronics or scrap metals, is then placed into the solution. The thiourea solution reacts with the gold plating and gradually dissolves the gold into the liquid.

Once the gold has dissolved into solution, additional refining steps are typically used to recover the gold from the liquid and convert it back into solid metal.

The general recovery process typically involves:

Preparing a thiourea solution in an acidic environment

Placing gold-bearing material into the solution

Allowing the solution to dissolve the gold layer

Filtering or separating remaining scrap material

Recovering dissolved gold through further refining steps

Because the effectiveness of thiourea depends on solution chemistry, temperature, and the type of material being processed, users should research proper refining procedures and safety precautions before use.
