High Purity Gold Powder With Oxalic Acid

Kevin @ 35:43 when sodium hydroxide mixes with your gold solution it creates a very dark purple coloured cloud. You can use that as indicator. If none forms that means all gold has precipitated.

I wanted to try the oxalic precipitation until I saw how difficult it can be. I think I'll leave it to the pros like you. That is the nicest looking gold powder I've ever seen..... Very Well Done!!!!

[@ProfaneGod]

The book suggested to pour the gold into the oxalic acid not the other way around like you did, that might be a variable to consider.

[@Joe.Rogan.]

37:44 It was cool to see what the Oxalic Acid pour off did to the temporary waste container contents. They were both clear before mixing then turned a dark redish brown when mixed.

[@MrRammsteinforlife]

Out of all the videos of gold refining that I've watched, when I start doing it myself I plan on following you and doing incremental nitric additions. 2 reasons. 1. Nitric is very expensive here in Australia ($100 for 5L) and 2. That it does seem better than having to add urea to the solution to remove the excess nitric.

[@Whosphatsony]

If you wanted to make sure you “stacked” safely, leave the gold at this “mud” stage of the refining process. This way, thieves don’t realize where your pure gold valuables are as it can be left out in the open in a vase with false flowers or some other kind of decoration. Or stop it at the liquid gold stage of the refining process and have it in an empty Jack Daniels bottle. So many ways to keep precious metals safe from thieves.

[@sreetips]

All good points

[@Whosphatsony]

Haha, thanks for responding! My points were probably ones you’ve already had. But thanks for letting me feel like I came up with something worth thinking about.

[@wethepeople7961]

I have yet to see you weigh the SMB prior to precipitation, there has to be a formula for accurate measures. this could prevent excess contamination.. the color is amazing...best one yet mr tips

I know nothing but I did notice in the book @23:31 that they suggested pouring the gold into the acid. Do you think that would minimize the spattering?

[@wolfedan3]

The main difference is that hydrochloric acid is composed of only HCl molecules, whereas muriatic acid is composed of impurities along with HCl molecules. Muriatic acid is often less pure and more diluted than hydrochloric acid.

[@PoorMiners321]

watching here very very nice video since the biginning i watch all your video sir so beautiful and very nice result, love your all video..

[@kieranodea771]

If your up for the challenge it would be great to see you refine gold using bromine. Elemental bromine is added to a flask with a little Hcl and very gently heated. Its best done in a flask with a condenser attached. Then filtered and precipitated with SMB

[@scott27288]

Maybe a dumb question but do you save the test strips with traces of gold on them the way you save your used filters and recover those trace amounts of gold later?

[@DeWin157]

I'm not an expert by any means, but do you think the lye precipitation would have been easier if you had diluted the lye first? It seems like that would have been easier to pour at a steady rate without producing such a violent reaction and could have made the whole process a lot simpler.

[@lazyman114]

Wow, I'd really like to see you melt that into a bar and compare it to your other high purity gold bars. I wonder how big a difference there would be. Also, the oxalic acid method probably wouldn't be too much of a hassle if you used your addition funnel.

Forgive me sir. You posted a video a while back. There was a bit about a passive silver coating on the copper used to cement out silver. I've ran almost two kilos and have had no issues with the cement process until now. The only thing I did differently was to reuse my copper wire . It was not shiny new copper. I'm kind of stuck right now. Should I add a bit of nitric to kick start the cement process again?

Highly concentrated silver solutions should be diluted before adding copper to avoid passivation. Not sure if adding nitric will help.

Is that gold powder gold oxide. That requires heat to make it regular gold. Or is it gold powder that with cold work would shine and sparkle. I’m asking because I want to try an art form called Kintsugi. And you put gold powder down onto lacquer and burnish it until it shines. So I’m trying to figure out how to make my own gold powder. I’ve tried sanding pure gold and using the bits from sanding but they are too large. Now that I see the sponge I’m thinking you can’t burnish gold sponge and get a shine.
