Gold Nuggets [Refining Raw Gold Into Pure Gold]

So what is the yield out of these Raw Gold Nuggets x 7 totalling 13 grams? Sorry you don't mention the weight of your endproduct nugget. The point here is to get an estimate of how pure is native gold. Thanks for any data you share!

I do believe the yellow may be iron. When beginning to see Crystal's in solution rehydrate with additional hydrochloric acid to dilute the solution and continue nitric boils. Inquarting seems to have save some time. Good job.

6:30 That yellow tinge is probably iron dissolving in the HCl. 17:30 I don't know if you noticed, but your nugget count went from 8 to 7.

Old timers would say gold rides an iron horse. HCL acid and iron will give you that yellow color.

The heavy elements that make up the Earth, including gold, were formed in the hearts of stars. Through nuclear fusion, the elements were fused together under intense heat and pressure. But, the creation of very heavy elements such as gold requires an even more extreme event: the explosion of a supernova 💫

Awesome Jeff , love all your pieces and videos, can’t wait for the next piece

Always enjoy your uploads. Many more are missing out and hope they find you like I did. Beautiful piece. Almost makes me want to send in some nuggets 😉

Just watched this again as I have been refining a few small nuggets recently. Western Australian gold seems to have bugger all silver and pd group metals so refining without inquartation works well with anything that tests out at over 85%Au.

So I know there was rock and what not in your initial weight so this value I’m about to give is a little off but based on that your starting gold was right around *18.8K. But the fact that you had a bunch of silver passivation issue when trying to dissolve in aqua regia, it makes me want to say it was less because you shouldn’t have any problem dissolving gold 18K or above (as 6k or below), but it’s possible there was just more silver concentrated in those nuggets in that particular area and not dispersed uniformly throughout. I wonder if you would have just melted them first and poured it into shot if you would have had the same passivation problem or not. Based off the numbers I would suspect not but it could go either way. Btw, Love your vids. I’m going to be honest, when I do my gold sponge rinses I’ve never done an ammonia rinse and have never had a problem with purity but I’m actually going to start doing that now because it does make the sponge look so much better/cleaner.

Great video, always a blast watching you work brother. What are the white circular pads your using for hammering and stamping?

Awesome video. Solid refining techniques. I'm guessing that was iron in solution. I was hoping to see you take a few drops of that solution and put it into a plastic spoon or spot plate. Then drop a couple Ferrous Sulfate Crystals in to see if they turned red indicating iron in solution. Lots of patience, distilled water, filter, wash & repeat. Fun stuff bro. Best wishes and keep that blus solution away from you skin...L0L

Got all this black sand with gold on it that is coating a lot of the artifacts. The stuff is just falling off, so I’m starting to bag it up. I have no idea how to turn all that gold dust into something sellable.

That's iron, witch you normally get from load gold vs alluvial gold, reason your seeing it in your acid is because you bypassed metallurgy before going to aqua Regia, the iron and other metals that are dissolved or vapored or inquarted before refining

I’m new to your page so forgive my ignorance. After you make these gold bars do you package and sell them? Also how did you get into making gold and silver bars? Are you a geologist? Sorry I have so many questions. If you’ve already answered these questions then just send me the link to it if possible. Thanks.

Just a thought, but it is possible for your nuggets to have nitrates or nitrites from the dirt they were in, and while it caused the "yellowing" of your hydrochloric acid, there wasn't enough of the nitrites or nitrates, to actually create Aqua Regia, however, was enough to cause the color change in the hydrochloric.

How do you test material before and after refining? Thanks for another cool video!

I could watch gold refining all day absolutely amazing it boggles my mind every time i see it and the final product is always stunning god i love gold! It is the most beautiful metal!

Iron is an easy guess as to what caused the HCl-aq yellow, although it could have been chlorine from tap water after you rinsed your breaker.

Use a cotton ball plug in your funnel when decanting off The gold powder to catch any gold particles.

Great video! Meticulous as always, love the process!! Thanks for sharing Jeff👊🏻👊🏻👊🏻
