Did you test for gold after the stump out with stannous?15. Added stump out to 50ml tap water and mix in to AR.
Yes, showed negative.Did you test for gold after the stump out with stannous?
Well that means that the Gold is converted to metal.Yes, showed negative.
That is the weird part. I get that grey sludge but ive waited a whole day. Negative reaction. And no gold dropped despite the stanneous tests throught out the process.Well that means that the Gold is converted to metal.
It is just not enough to see it yet.
Let it sit over the night.
I have to be honest in that I'm not seeing the logic in this. Steps 7 and 8 are inefficient if you are going to use AR anyway. I'd save yourself a lot of time and effort and cut them out and use Nitric for the AR or not use it at all.I am not using poor mans nitric. The ratio i used was making poor mans AR.
Its very hard for me to get Nitric Acid so after a nitric acid wash, i try to use sodium nitrate and HCl to make poormans AR for the gold recovery bit.
Yes..I was wondering the same thing.Can I ask why you're washing in Nitric yet then using Poor man's Nitric to AR?
I have read that using " city water" may create a weak AR when used with Hcl. Due to the chlorine in city water/ tap water. Depending on what step I'm on during my process, I may use city water. But also I keep a bottle of distilled water too.And never use tap water. City water can have chlorine and other additives such as fluorides, well water will have whatever has leached from the surrounding geology, which could be any element(s). Distilled is the way to go.
If you introduce Chlorinated water into Nitric you may create a weak form of AR.I have read that using " city water" may create a weak AR when used with Hcl. Due to the chlorine in city water/ tap water. Depending on what step I'm on during my process, I may use city water. But also I keep a bottle of distilled water too.
City water that has chlorine in it will do no harm if mixed with HCl, which already has chlorine in its make-up. However, if you mix chlorinated water with nitric acid, you can create a weak AR.I have read that using " city water" may create a weak AR when used with Hcl. Due to the chlorine in city water/ tap water. Depending on what step I'm on during my process, I may use city water. But also I keep a bottle of distilled water too.
I have incinerated 10 CPU pinned chips, and 100 grams of IC chips. And 3 BGAs
This is exactly the amount i was looking for. I was expecting .3g at least as i did this exact size before and dropped .34g. Thanks for everyones recommendation on city water (im a city boy haha) i got 2 distilled containers now and will be using it on Nitric only/ ARHey guys I think this is a problem of resolution. How much gold was your expected? How much gold do you think is in 100 grams of random ics? Your gold probably did drop out of solution. Depending on what you started with 50-100mg might be all that you got.
So i did 2x hcl washesYes..I was wondering the same thing.
Quick question: So i understand i need to heat HCL and Sodium Nitrate to make poor mans AR (70-80 degrees).There is still Gold, but switching back and forth between HCl and Nitric is almost guaranteed to create losses.
Unless you roast the material in between.
Wash it well in HCl pour the used HCl into a container and add fresh HCl, then drip in Nitric untill all foils are dissolved.
Or even better, use Peroxide or pool Chlorine in sread if Nitric.
No risk of excess Nitric then.
I have not used poor mans AR.Quick question: So i understand i need to heat HCL and Sodium Nitrate to make poor mans AR (70-80 degrees).
Do I need to heat if i am dripping nitric acid into HCl to form AR (the true AR method)?
Alright so this is my second time with expectation of very VERY low gold drop.There is no ideal so to speak, but it has to be acidic so the SMB produce SO2 which is the active ingredient.
So Usually lower than 4 but even better in the 2-1 range.
