At Chips Etc. we often get inquires into what is the value of gold found in vintage computer chips and other electronic items. How to Recycle Gold From Old Computer Cpu mobile phone recycling process. There is very little profit from extracting the gold content found in most computer chips and electronic components yourself unless you have significant quantities of them to be processed. Refining Gold & other precious metals (including silver, palladium & platinum) from CPU's & electronics is typically not profitable unless it's done professionally and in large quantities on a large scale; when processing just a few items the cost is often higher than the value of the gold that is reclaimed. More importantly, the process of refining gold involves working closely with hazardous materials including nitric and hydrochloric acids, as well as Mercury, and should only be performed safely by experienced Gold refiners.  e book gold extraction process recover gold refinery gold refining gold recycle gold recycling. gold extraction ebook pdf. chemistry of gold extraction ebook.

Aqua regia (Latin, lit. "royal water" or "king's water") is a mixture of nitric acid and hydrochloric acid,optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange fuming liquid. Aqua regia was so named by alchemists because it can dissolve the noble metals gold and platinum. However, aqua regia does not dissolve or corrode silver, titanium, iridium, ruthenium, rhenium, tantalum, niobium, hafnium, osmium, or rhodium.
Applications
Aqua regia is primarily used to produce chloroauric acid, the electrolyte in the Wohlwill process. This process is used for refining the highest quality (99.999%) gold.
Aqua regia is also used in etching and in specific analytic procedures. It is also used in some laboratories to clean glassware of organic compounds and metal particles. This method is preferred over the "traditional" chromic acid bath for cleaning NMR tubes, because no traces of paramagnetic chromium can remain to spoil spectra. While chromic acid baths are discouraged because of the high toxicity of chromium and the potential for explosions, aqua regia is itself very corrosive and has been implicated in several explosions due to mishandling.
Due to the reaction between its components resulting in its decomposition, aqua regia quickly loses its effectiveness (yet remains a strong acid), so its components are usually only mixed immediately before use.
While local regulations may vary, aqua regia may be disposed of by careful neutralization, before being poured down the sink. If there is contamination by dissolved metals, the neutralized solution should be collected for disposal.
Chemistry
Dissolving gold.
Pure gold precipitate produced by the aqua regia chemical refining process
Aqua regia dissolves gold, though neither constituent acid will do so alone, because, in combination, each acid performs a different task. Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold ions (Au3+). The hydrochloric acid provides a ready supply of chloride ions (Cl−), which react with the gold ions to produce tetrachloroaurate(III) anions, also in solution. The reaction with hydrochloric acid is an equilibrium reaction which favors formation of chloroaurate anions (AuCl4−). This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloroauric acid. In addition, gold may be dissolved by the free chlorine present in aqua regia. Appropriate equations are.
