Good to know. Now I need to memorize your information! LOL Thanks.Elemental sulfur has nothing to do with the reaction of precipitating gold from the solution.
It is a gas called sulfur dioxide (SO2 gas) that is created from the chemical reaction of the sodium metabisulfite and the acid reacting together, along with another byproduct of this same reaction of creating sulfuric acid in solution which can be beneficial for several reasons (when the evaporating solution to remove free nitric or de-NOx, and in helping to remove lead ions from solution as a sulfated salt of lead.
We can also produce or generate SO2 gas by other methods like burning sulfur in a generator, or in a lab, with a dripping apparatus using a sulfite like SMB and acid, or we can also just buy bottled SO2 gas...
Sulfur is not created in these chemical reactions, and sulfur has nothing to do with precipitating the gold from the solution.
I thought about that because I have crushed tons of gold and silver one but was not to sure if it would work thanks for the information he does have a cement mixer he got from a trash out he will try thatIn nature placer gold settles onto bedrock, you can mimic this procedure by ball milling your gold covered china dry.
Add the milled powder into a large flat bottom plastic container then add just enough water to make the heavies mobile.
If you do not have a vibrating table, stow the container in the back of your truck or trunk of your vehicle for a week soon you'll have a layer stuck fast to the bottom of the container.
Scoop away the waste then enjoy the fruits of your labor.
