How to #refine #gold scrap into pure 24kt Gold
2 OUNCES of gold are refined in this video. I show all the steps to refine karat gold scrap jewelry into 999 pure gold using nitric acid and aqua regia. First, the gold is inquarted with sterling silver to reduce the gold content in the alloy below 25% so that when dissolved, the nitric acid can fully penetrate and remove the unwanted base metals. Next, the gold is then further refined in aqua regia to produce 999 fine gold.
The two acids which are used in this process are hydrochloric and nitric acid. Nitric acid is very corrosive and when combined with hydrochloric acid, creating aqua regia, it becomes an even stronger acid capable of dissolving gold. Process should be performed outdoors or under a vent hood. If you're using a nitric acid substitute, it should still be outdoors, or within a self-contained system that neutralizes fumes. Always be sure to use proper safety protocols including PPE.

I love to see that color change after the first spoonful of the SMB is added so awesome.👍

Good job. I've always liked cleaning the copper and silver out with Nitric Acid first, I am not sure why so many people dont do that.

Thank you for subscribing! Many ways to clean up gold and I think this is my favorite way too.

Fellow yourube refiner! Great video! New subscriber!

Awesome! Thank you!

Do you have a video on how to dispose of the chemicals. I read that to neutralize the aqua regia you would need sodium bicarbonate but it didnt say the process. Before i get into refining i want to know the safest waste practice to protect the local environment

We never got to see how good your guess was on cutting that bar at the end. Lol

If I recall, I was off by about a quarter inch! Lol

No stannous chloride test? 😮 Kind of sure of yourself aren't you...? 😊😅😂

What happened to your chute you made to make silver shot. I figured you would use that after you melted the gold with the silver to form the shot. Glad to see your back now…Love your videos!

Thank you! Got one coming up in December with the lava slide.

Very nice... pure gold color is so goldy... is better pour shot or roll thin sheet?

@monadnockgems 8 месяцев назад

Thank you! I haven't found rolling truly saves much acid and can take a little bit of time depending on your roller. (My roller's manual) Pouring shot is definetly easier.

Is it possible to part inquartered gold using something other than nitric acid like maybe piranha solution or anything else? Nitric acid is just very expensive and I don't have distillation apparatuses and everything required to make my own of sufficient quality but I can easily get my hands on sulfuric acid and possibly others that aren't so restricted and / or costly

Inquarting gold then parting it with nitric acid then refine it with aqua regia, how much purity we can get from these steps, is it always more than 999 purity? Cause I see most of refiners do the same process but they refine gold 3 times in aqua regia which consume a lot of time and acids

@monadnockgems 21 день назад

Good question... Not always 999, depends on your procedure and the material I start with. Gold plated will always take more steps than karat gold because there is so much more base metal. Perfect procedure also makes a difference vs sloppy procedure. Ultimately you can get 999 with one refining if you start with cleaner gold and you use your very best procedures. Thanks for watching!

Uses aqua Reja gold button doesn’t dissolve can you explain this please?

@monadnockgems 2 месяца назад

Pure gold should be combined with silver to dissolve properly. AR is poor at dissolving pure gold. I suppose it would dissolve over a period of time but combine with silver then go nitric to remove silver then the gold is broken down into its cement form and AR works fast on it then.
