ЗОЛОТО С ИМПОРТНОГО ЧЕРНОЗЕМАAdded:
Hello everyone, friends, subscribers, and guests of my channel. I have this material from a subscriber of an imported microcircuit.
They are not bitten.
This is the quantity.
I started eating them, checking for malware, but my eyesight isn't what it used to be. It is not clear where the gilding is and where it is not.
I decided, in general, to burn and cook them all together.
Now, friends, let's hang out with you and find out how much material will be recycled.
Bye, friends, if you haven't subscribed yet, subscribe to my channel.
Don't forget to like, dislike, comment, and write that there's little that's popped up. You can already see everything better there, right?
Apparently, it's a microcircuit like this, but I bit it, it does n't have a winding inside.
So, friends, let's hang out with you now.
It all won't fit here.
Here they will fit.
Now I'll find some kind of container and we'll hang it up. So, friends, I found So, friends, I found this hole.
Now we will cover all this material with you. We find out the amount of material to be processed.
There are even some that seem to have conclusions written on them, but I doubt that they are written.
We'll see this one and this one later.
And that, friends, is 623.4 g.
We see.
Now I’ll go and burn everything and then I’ll show you what I’ll do next.
I prepared this microcircuit. We can already see that we have this much material.
There are some that come with a ring.
In general, now I will pour it into this glass before etching.
I had already poured electrolyte there in advance.
I'll carefully transfer this material here. There is enough for now, I will add more later when it gets better.
And pour nitric acid. That'll be enough for now.
I'll put it all on heat.
The reaction has already begun, I see. I turn on the stove.
Let it warm up.
And I will now bring this call into this glass.
Here.
And I'll pour some Sorsk vodka there.
I removed the gilding here.
Apparently, this is how much it turned out to be. And here's another thing about filters. Now I'll move the filter here. I'll fill it all with hydrochloric acid, a mixture of both. In general, I’ll open the vodka and let it dissolve.
When friends dissolve, [music] I will show you everything that I will do next.
Now I'll carefully assemble this podbedka onto the filter. That 's it, friends, this time filter is there. Di is so impudent. Doesn't want to die.
I pour hydrochloric acid here.
Enough.
And I'll zot a little.
Basically, I'm making aqua regia.
All.
And I put it on to warm up.
I'll cover what's on the walls, it will dissolve under the steam, and will sink to the bottom due to the actions on the frames. This has been tested more than once, so you don’t have to write there and tell [music] fairy tales. That's it, it's cooking.
I filtered these solutions. Here now the iron is being filtered from sago. This is from the ashes.
Now I will add zinc dust here. The other day I received zinc dust.
Here we see zinc oxide.
Дуже отруйно для водныхического деятельности.
Here's a little bag like this one. That time I came to the box and that's it.
Well, now, friends, I’ll take a little spoonful of zinc dust and sprinkle it here.
Probably, friends, I eat azodki.
Well, everything is fine now.
I threw a little more and that was it.
I always throw with a reserve.
Then I'll show you what I'll do next.
I'll put it on overnight. Let all the gold that is there fall out. And here, probably, the same thing applies to the chain-digger and that's all.
We see that the solution has settled overnight.
This is how much gold fell.
Now I'll carefully run this through the filter [music].
Well, I’ll boil the liquid itself, what remains on the filter, [music] later.
And the solution itself is prokichu in distilled water. Okay, [music] a few times. And I'll show you what I'll do next.
That's not gold, that's trash.
What was left on the walls [music] was, what was it called, zinc dust. Well, something like that. That's it, I boiled it with distilled water, water. We see this kind of deposit.
I'll add nitric acid here now.
Although you can add salt, I will add nitrogen. If there is copper there, the copper will dissolve and there will be pure gold.
Enough.
And the same thing here. Well, here we see a lot of zinc powder. Now there will be no zinc to get rid of.
the reaction began.
The price tag will now flare up and there will be a gold sediment.
Then I will collect these two sediments together, dry them and melt them. I'll show you the result.
Re-dissolved this sediment.
Now I'll be a little bit more funny about hydrahydra.
I added some iron from the ashes there.
We see, friends, that he has begun to recover.
Another control one. That's it, all the gold has fallen out.
When I fuse it, I'll show you the result.
Идим зань кокулки уже есть кокулечки. Here are some poops, poops. Here. Well, something like that.
When I float it down, I'll show you the way out.
melted this gold from these microcircuits.
Now we will find out how much gold I got. Here, apparently, is such a small drop.
Now, friends, let's hang it out with you.
We see 0.451.000 per gram.
As for me, the result is normal. there was such a quantity of micros and such material. Half of them were there, even more than half were not gilded. Well, something like that.
Everyone who liked the video, give it a thumbs up. For those who don't have the option to subscribe to my channel, please do so. Peace, goodness, and most importantly, health to everyone. If you have health, you will have everything. Take care of him.
Bye-bye everyone. See you soon.
