This one was a major undertaking. I had to clean my bench you saw in the previous video, setup a second cell, and get it all edited for the forum.
It was a pleasure to make this one, I'm very proud of it.

I've also started working on a mini-tutorial on separating silver from gold and precipitating the silver.

STEVE NICE JOB ON ALL THIS

3 QUESTIONS

1-IS THERE AN ODOUR OF ANY KIND

2-SULFURIC ACID WHAT WOULD BE THE BEST DRAIN OPENER FOR THIS

3- SULFURIC ACID WHAT OTHER ITEMS CAN REPLACE DRAIN OPENER
CAN I USE BATTERY ACID FROM AUTOZONE, OR USE Sulfonic Acid
 
I think I can answer those questions ;)
-Sufulric acid smells something but it's not that bad.
-Try to buy a drain opener who has the purest sulfuric acid. Sometimes they add inhibitors and it's not good. Mine has only a colorant but it is +90% Sulfuric acid.
-Car battery acid is surfuric acid but it is too weak. Buy drain opener liquid instead.

Voila !
 
THANKS NOX

I HAVE MINE COMPLETLY SET UP

NOW ILL WAIT TO SEE HOW IT IS PARTICIPATED

WOULD IT BE THE SAME WAY AS AQUA REGIA

AFTER WE PUT UREA IS IT SAFE TO ADD WATER
 
Great job on the reply Noxx! I have a small bit to add.

PM,

If you have the cell covered for some time it will emit an egglike odour for a short time after you open it. I just open the balcony door while I work.
Also, if your anode arcs at all you can get the same odour.

PM,

there are differant teqniuqes to precipitation, if you using a cell you wont need urea. An easy way to do it is diulte the eloctrolyte in water, 5 parts water for 1 part electrolyte (generaly, you could probably get away with ten cups water for 3 cups electrolyte). Do this in a ventilated area and in a jug or something that can hold up to a little heat because water and sulfruic acid react and heat up slightly.

Let it sit still for around 24 hours and the go into filtering it slowly, once filterd check the filtered solution for remaining gold either using test liquid or refiltering for good measure. Steve said 5 coffee filters works best and i trust his judgement and have upped my filters content to 5, The rest steve has listed in a video clip in the section.
 
OK SO YOUR SAYING MIX 10 CUPS OF WATER FOR THE 3 CUPS OF SOLUTION, LET IT SIT FOR 24 HRS AND THEN RINCE WITH 6 COFFE FILTERS.
 
PM,

The electrolyte is only diluted AFTER you finish filling your cell. Your cell will not fill very rapidly unless you spend a lot of time stripping scrap in it before you process it to retrieve the gold. The gold is in the cell as black powder and NOT dissolved in the electrolyte. The reason the electrolyte is diluted after the cell fills is to slow the acids attack on the filter and to make it thin enough to pour thru the filter in a timely manner. I usually run a cell for 12-20 hours of actual operating time before diluting and filtering. Of course the amount of gold obtained in this time depends on the quality of the scrap processed.

This is a snapshot of a fresh empty cell:

I will be filtering my full cell on video for the forum as part of this tutorial. It is pictured here:

This 'loaded' cell should contain between 15 and 30 grams of gold if my estimates are correct. I'm debating trying a new cleanup process based upon some on the forum posts by Harold. He mentions soaking the black powder in nitric acid before the final smelt. We'll see how time permits.

steve
 
The nitric acid soak is a good idea. Maybe you could also try to soak it in ammonia to get rid of other metal oxides ?
 
thanks steve cant wait to see your filtering video

so far all your videos are explained to the point

good work

thanks for being on this forum
 
PM,
that for precipitating, but yes your rite. Steve is gonna post a vid its seems so if you wanna see it step by step he'll get you takin care of.

I think Harold plan of nitric acid is ingenious and I olan to incorperate it into my next batch to see how it goes, that will definiatly make things cleaner.
 
HOW TO MAKE NITRI WOULD BE GREAT .

BUT DOES ANY ONE KNOW,

WHATS THE DIFFERTS BETWEEN, NITRIC AND ACID TO MAKE AQUA REGIA,

AND SODIUM NITRATE AND ACID TO MAKE AQUA REGIA

WOULDNT IT BE THE SAME

IT BOTH BECOMES AQUA REGIA
 
-No, salt doesn't affect the acid.
-I'm pretty sure you can process gold filled too. Give us the results you get.
Good luck !

I need to use car battery acid on one of the final steps to wash the gold before it is melted, can you recommend a over the counter brand of drain cleaner that only contains sulfuric acid or has the least amount of other chemicals?

This may be a stupid question but ammonia is used as well to wash the gold, is there different strengths that are available or is the ammonia you will get in the grocery store pretty much pure?
 
Rooto brand. In liquid form.
Try Ace Hardware, True Value Hardware, or a hardware store that sells the "Do It Best" line of products
 
NEED HELP VERYFING I JUST BOUGHT DRAIN OPENER WENT THROUGHT DOZEN OF THEM BUT NONE STATES SULF ACID THERE ALL SODIUM HYDROXIDE AND POTASSIUM HYDROXIDE WHAT BRAND WOULD HAVE SULFERIC ACID
