How to recover gold from aqua regia, learn about How to recover gold from aqua regia, ewaste, chips, CPU, xray films, photographic waste, aqua regia, cyanide solution, circuit boards and RAMS. Recovery methods extract or recycle of precious metal like Palladium, Silver and Gold.
By using our Safe Gold Refining Technology products, the jeweler or refiner eliminates the production of toxic fumes. Nothing like Aqua Regia, Miller process, inquarting parting process, with large quantities of toxic fumes produced, toxic gases, boiling acids.

even more importantly you cannot lose any gold by making a mistake aquaregia can be toxic at times and the smell is awfull. also with aquaregia you are desolving the gold,so there are alot of variables that can cause loss of your gold. my system uses a safe nitric sustitute. here is how you can make the acid.
Sep 25, 2011018332Interestingly, diluting the acid mixture with water causes the gold to solidify back out in metallic form This can be prevented by using a solution of potassium permanganate instead of the plain water, or by boiling ammonium sulfate with the acids before diluting. Mixtures of manganese dioxide and sulfuric acid can also dissolve gold.
The appearance of noxious fumes during the processes of dissolution and gold reduction is a major impact of the aqua regia gold refining system and may cause large investments in NOx scrubbers which may even exceed the investment into the rest of the process by far if the process has not been designed carefully.
recovery and refining gold (instructions for aquaregia refining) materials and mixing instructions if you need supplies go to our store enter the store aquaregia if you are only after gold the first optional steps can be skipped 13 ounces of metal per quart of ar. will desolve properly without loss.
An alternative to aqua regia is to use hydrochloric acid and bleach, the bleach breaks down in the acidic mixture and gives off chlorine gas. This has the power to dissolve gold but not as fast as aqua regia. Often used on gold foils or powders. Hydrochloric acid and hydrogen peroxide (Main article Dissolving gold with hydrochloric acid and
