As the gold cements back out on the baser metals, via the principles of the reactivity series of metals. What did the stannous test say? Before and after? What does the insoluble powder look like? Gold plating is incredibly thin, 30 microinches or less usually, so it takes a great deal of pins to get any decent sized button of gold.

The alcohol either kind will work, if used, the idea is to initially wet the gold with a flammable material that will do no harm or add anything, but can be helpful to burn the paper to carbon and thus ash, and help wet the gold powder to initially help hold it together helping to keep the powder in the dish from the force of your torch.

I can see it being used for the crucible and maybe putting it in the bath water to help keep the gold from floating away. Other than that, it's probably a Borax commercial. I still have dirt that I classified into 5 classifications and I'll maybe do one batch of dirt to see if it'll help make the gold stay on the bottom in the water.
Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals.

Aided by the surfactant, the water repels the gold into the air bubbles, which rise to the top – creating a bubbly golden froth. The froth is skimmed from the surface and collected …
Discover top 3 easiest ways to refine and purify gold (using acid, fire, and electricity). The gold purification processes explained in this guide! ... and a heat-resistant surface to work on, like a lab bench or non-flammable table. ... Give the yellow particles a good rinse with distilled water to remove any leftover impurities or chemicals.
The bits doing the work are the ions that occur when these things are dissolved in water, namely the Cl-. and H +. Acetic is a relatively weak acid with a pKa of around 5. That means that it does not fully dissasociate into H + and an acetonium anion, when dissolved in water. Because of this, chances are that you'd need more vinegar than ...
The idea behind using SMB is to selectivly precipitate gold. The SO2 created by SMB is what does this. While sodium bicarbonate will precipitate gold out of solution, it will precipitate everything else as well and put you right back at your starting point. Oh, and it is "baking soda", just so you know
Gold processing - Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two …
In nature, gold nuggets are not pure gold. They are a combination of minerals, known as ore. The metal can be removed from the ore in a process known as smelting, in which the minerals are separated by melting point. Smelt gold is more pure than the original ore product, but can still contain impurities such as sliver, copper and platinum.
Gold processing - Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine …

Overall, if you can afford the initial investment, the cost difference between a salt water pool vs. a chlorine pool evens out over time. Given the lifespan of a salt water generator and how often you'll need to repair or replace parts, you'll probably spend the same as you would maintaining a chlorine pool.
Hello all, I've been letting my gold fingers sit in HCL with an air pump for a while now, about half of them are off. I recovered a first batch of them by switching buckets, rinsing with water and using a paper filter to catch the foils, it worked pretty well. The water I …
Silver and gold do not separate easily if they are alloyed together. Learn how ancient metal workers used salt cementation to extract pure gold from electrum.
Most Used Gold Refining Methods. The methods that are most commonly used are the Wohlwill and Miller process. The Wohlwill process increases purity by up to 99.99% by electrolysis. The impure gold is put in an electrolyte solution of gold chloride and hydrochloric acid. ... Can You Wear White Gold in the Ocean/Salt Water? You can wear white ...
But you need to add about 50% water to the HCl (always add the acid to water first!), because water holds more base metals in solution than an equal volume of concd. HCl. The lower concentration of HCl will not slow down the leach. Also you will get a lot less fuming. You can speed up the leach by adding some peroxide (H2O2), and some heat.
like if you add sodium hydroxide (NaOH) to hydrochloric acid (HCl) to neutralize the acid to a Ph of 7 you end up with salt water --- NaOH + HCL goes to NaCl (table salt) + H2O = salt water --- evaporate the water off & you end up with table salt that's way you can make nitric acid by adding potassium nitrate or sodium nitrate to sulfuric acid
also metals are positive and acids are negative the come together to make a salt example copper Cu (+)and ntric acid HNO3 (-) make a salt of copper nitrate Cu+NO3-, or if we mixed hydrochloric acid HCL and NaOH caustic soda (sodium hydroxide)(lye)(red devil drain cleaner) together we make somthing we eat on our french fries, --HCL + NaOH-->NaCL ...

Salt NaCl and nitric acid HNO3, would make an HCl, HNO3 and sodium in solution, basically a form of aqua regia, since the gold was very thin it dissolved in this solution and plated back out on un-dissolved base metals, the only way to get it back would be to dissolve every bit of base metals, the problem with whole circuit boards is there can be base metals deep down …
Scott, You are correct that it is the iron in the copperas that precipitates the gold, here is something else to consider, if you have gold and platinum in solution, ferrous sulfate will precipitate the gold but not the platinum (platinum is below iron in the reactivity series), if we added a bar of elemental iron to the solution of gold and platinum, the iron would give up …
If you use the excess oxidizer in the cupric chloride leach (AP), such as too much H2O2 (generating chlorine strong enough to put some gold into the solution) some of the gold can dissolve, and most of the time the undissolved copper will displace this gold (cement it back out of the solution) as black powder, but if tin from solder is ...
You wrote your last reply before I could post this,but here is my reply to the first post. Muriatic can dissolve gold,if enough oxygen is introduced.However you would need to introduce a lot of oxygen yourself,usually with a mechanical aid,or dump an overabundance of peroxide into the mix.But unless you are dumping large quantities of concentrated (I use 35%) peroxide …
