Nitric Acid and gold pins

2 cups of distiled water, 2 cups of nitric acid and about 1lb. of gold plated pins. I tried this on 1 oz of pins and all that was left when finished was the gold plate. Everything ells was dissolved. sorry about the resolution I tookl the video with my phone.

Sorry to say I still have not completed this project. It is still sitting in solution. The board is out of an old computer main frame (20 years old) before the plating was minimized to nothing in gold content. The point of distilled water is to minimize additional contaminates in the water,IE chlorine. boiling or letting regular tap water sit for a minimum of 24 hours allows the chlorine to off gas. I am currently working on a chlorine based PM extraction process.

In a few weeks I will be posting a video of the mill I have been rebuilding for the last year and a half. Much safer than this method of extraction. Dirt to gold or any sulphide I choose to precept out of solution including base metals lead, arsenic, iron or what ever. 80 to 100 % recovery every time. Everything I recover has a market to sell too. 0 waste to dispose of. This is the only working mill of its kind on the planet. Stay tuned if your not to pissed at me for this stupid experiment.

Afternoon All. Whell I did not have the lid sealed it was just sitting there. I can't help people that have not the intelligence not to put this down the drain.The solution is still in storage at work in my lab. I did process the other side of the circuit board In nitric acid only. recovered 3.6 g less than 1g troy oz. smelted, about $60 worth. A pea sized ball. It was fun for me while I built my processing mill. I will not be doing this type of gold extraction again to many things to go wrong

@betadoctor HAHA I know :) ive been doing it for 5 months now.

@naanaa1111 Gold plated pins, stripped from high grade circuit boards (read PC Mainboard's etc..)

@jaws99099 It's called 'goldfever' and it is a disease with no cure known to man ..

plus .. your dollar (or whatever currency you are used to) will be worthless in the next 10 years. I'd go for PM's any day.

[naanaa1111]

what kind of "pins?"

[tozlu10]

ok first thing you did wrong was you dissolved gold with nitric acid in a old jelly jar. the heat and pressure from nitric acid could destroy the jar. also the purpose of using nitric acid is to remove non royal metals so that metal top lid would in a short time dissolve. adding water to nitric acid only reduces its potency and is a huge waste of money. getting nitric acid ship and bought run over 130usd. you should only cover nitric acid with like a heat resistant plate like plexiglass.

Dude, carefull with putting a cover on it could explode. I found a wet rag works just fine. Check out my vacuum assisted gold filter on ebay under mojo757. It works real good.
