If you leach with aqua regis (nitric and hydrochloric acids), you can precipitate the gold with sodium metabisulfite (a reducing agent). Mixing muriatic acid (hydrochloric acid) with bleach (sodium hypochlorite), you are freeing chlorine to attack the gold. You are making gold chloride.
Working with Hydrofluoric Acid It is extremely expensive around $130 per half litre and very dangerous. Udo has a permit to use this acid and he does to clean his gold but we do NOT recommend its use for untrained people. Remember too that you cannot purchase it without a permit. Return to Gold Prospecting home Page from cleaning gold page.
Suppliers of hydrochloric acid sell it and transport it in liquid form with a concentration of up to 38%. Hydrochloric acid is one of the simplest anaerobic acids. It belongs to monoprotone mineral acids, but in this group, it is distinguished by its unique features. It has strong corrosive properties and is characterized by a pungent odour.
Actually hydrochloric acid by itself does nothing itself to help refine gold. It is a good cleaning agent to remove residue from the surface of gold particles allowing them to be more easily amalgamated with mercury, but white vinegar works nearly as well for that purpose. Gold as found in nature is rarely pure.
Then add another 1/2 cup of water to the blender container and rinse the residue into the 1 gallon jar. Stir the sodium nitrate and water mix and let that sit for at least 1 hour. Now add 1 quart of sulfuric acid (auto battery acid). Stir the solution a couple times and let it …
Answer (1 of 2): Aqua Regia solution which can dissolve gold into liquid form. Aqua regia 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, so named by alchemists because it …
2. Pour the shot into one or more Pyrex or plastic containers. For every ounce of scrap gold you are going to refine you will need a capacity of 300 milliliter. So, for example, if you are refining 10 ounces, you need a 3,000 milliliter (3 liter or 3 quart) container. 3. Add your reagent to the container.
Product Description: Hydrochloric Acid also know as muriatic acid is a colorless, inorganic highly corrosive solution of hydrogen chloride in water. Hydrochloric Acid is classified as strongly acidic and has a very distinctive pungent smell. Hydrochloric acid is the simplest chlorine-based acid system containing water.
Mar 31, 2021· Aqua Regia HNO 3 + 3HCl is used to etch gold or platinum. It is a mixture of Nitric acid and Hydrochloric acid that is freshly mixed before use. Optimally it is in a molar ratio of 1 part nitric acid to 3 parts hydrochloric acid. When freshly mixed is clear, turns yellow very quickly and eventually red.

Answer (1 of 5): It's so far at the other end of the scale from simple it's not funny. Quickly without the use of nitric acid this procedure is because nitric acid is hard for obtain. So firstly hydrochloric acid three parts of 4 and the other part peroxide. (Will go …
You can start the process for the magnetic pieces similar to how the acid peroxide/copper II chloride works. The magnetic base metals will dissolve pretty easily in just straight HCL on sustained heat freeing up the gold foils. The not magnetic scrap can be treated with dilute nitric leaches.
Hydrochloric Acid Used in Gold Mining is widely w idely cognitived as the most economical acid used for the treatment of ore removal from the mining Hydrochloric acid is used in many process of Gold Mining Treatment, including the extraction process, the separation process, the purification Processand the Water Treatment Get Price
This is an alternate method to using AquaRegia. The problem with using acids like this with "gold ore" is that other metals are almost always present in the ore with the gold, so once you dissolve the gold into solution, other metals are also spoiling the mix, which makes removing the gold even harder to do. Sulfuric Acid will "not" dissolve gold.
Pre‑elution treatment of activated carbon in gold mining. The mining industry relies heavily on the acid leaching of certain minerals from ore deposits, an economical method of recovering valuable minerals from otherwise inaccessible bodies of ore. Hydrochloric Acid can be used in the following stages at the mine: Acid Washing; Acid Wash Cycle
Using only the HCl acid (muratic) will normally breakdown the rock/silca which encases the gold. but HCl is also used to remove/dissolve the base metals associated with plated gold. And then further refined by placing the gold recovered into a solution of HCl and bleach, which will dissolve the gold into the solution.

For a refractory ore, pretreatment is required in order to expose the gold surface to the leach solution. An acidic hypochlorite solution can be added to the autoclave for pressure oxidation and extraction of the gold at the same time. It required 50 % sodium hypochlorite or 120 kg/t available chlorine to extract 97 % of the gold from the ore.
