The JSP® Aqua Regia Gold Refining Kit is a premium solution for professionals seeking to refine gold with precision and safety. This kit includes two high-quality acids:

• Nitric Acid (69.8%) – 32 oz.: A potent and highly corrosive mineral acid, nitric acid is essential in the gold refining process. It acts as a powerful oxidizer, facilitating the dissolution of gold when combined with hydrochloric acid to form aqua regia. This lab/technical grade nitric acid is suitable for various commercial applications and research laboratories.

• Hydrochloric Acid (31%) – 16 oz.: This strong, corrosive acid is a key component in creating aqua regia. When mixed with nitric acid in a 3:1 ratio, it forms a solution capable of dissolving noble metals like gold and platinum. Hydrochloric acid also aids in removing impurities during the refining process, ensuring high-purity gold recovery.

Understanding Aqua Regia:

Aqua regia, Latin for "royal water," is a highly effective mixture of nitric and hydrochloric acids, typically in a 1:3 molar ratio. This potent combination is renowned for its ability to dissolve noble metals such as gold and platinum, which are otherwise resistant to single acids. The freshly prepared solution is colorless but rapidly turns yellow, orange, or red due to the formation of nitrosyl chloride and nitrogen dioxide.

Safety and Handling:

Both nitric and hydrochloric acids are highly corrosive and should be handled with extreme caution. Proper personal protective equipment (PPE), including gloves, safety goggles, and lab coats, is mandatory when working with these chemicals. Ensure that the refining process is conducted in a well-ventilated area or under a fume hood to avoid inhalation of harmful vapors. Always add acid to water, never the reverse, to prevent exothermic reactions that can lead to splashing. Store acids in appropriate, clearly labeled containers away from incompatible substances.

Applications:

This kit is ideal for:

• Jewelry Manufacturers: Refining scrap gold or defective pieces to recover pure gold for reuse in new creations.

• Electronic Recyclers: Extracting gold from electronic components and connectors, capitalizing on the value of precious metals in e-waste.

• Laboratories: Conducting experiments and research involving noble metals and their properties.

Note: Due to shipping regulations, these acids can only be shipped via ground services to the contiguous United States. They cannot be delivered to P.O. boxes, and delivery times may be extended. Ensure compliance with local regulations and guidelines when purchasing and handling these chemicals.
