Description: JSP is the largest manufacturer of supplies for the jewelry industry.We created this kit for you to perform scrap gold recovery. Sodium metabisulfite is commonly used to precipitate dissolved gold out of aqua regia and gold chloride solutions. When it is dissolved into water, sulfur dioxide gas is created which is excellent at precipitating gold from the solution. Sodium metabisulfite is a popular choice in this process because it is more selective in precipitating gold by itself. In the process of gold extraction from e-waste and scrap gold recovery, Sodium Metabisulfite is usually used along with Urea. Urea, also called carbamide, is soluble in water and alcohol and is non-combustible. In gold recovery processes, it is used as a neutralizer of excess nitric acid in aqua regia solutions. General instructions are included giving a short overview for performing gold and other precious metals precipitation from aqua regia solution. Links to more in depth websites are also included. To make aqua regia solution you will need concentrated hydrochloric acid and concentrated nitric acid (for nitric acid, please see sciencecompany.com). These chemicals are sold separately from this kit.
