00:00Guys, in today's video, we are going to extract gold.
00:03So for this, we have a lot of computer parts here.
00:08We have mostly taken RAM.
00:09And these parts are all broken, these are computer parts.
00:13And these parts have gold inside them.
00:16Yes, guys, gold is a very good conductor.
00:20That's why gold is used in a lot of parts.
00:23And what we are going to do in today's video,
00:25we are going to extract that gold from all these broken parts.
00:29However, the price of all these RAMs is Rs. 20,000.
00:33We have bought this cupboard for Rs. 20,000.
00:36Now we have to see how much gold will be extracted from these RAMs.
00:40But how will it be extracted?
00:41That's what we have to see.
00:43That's why watch this video till the end.
00:45And like this video right now.
00:46It's going to take a month.
00:48The video is only 10 minutes long.
00:59Step first.
01:29Music
01:39Guys, now let's put all these RAMs in this solution so that the reaction can start.
01:43Guys, here the metal is reacting and hydrogen gas has started forming in the form of small bubbles.
01:48It went inside this solution.
01:50And now we have to keep this solution for about 6 to 7 days so that the reaction is good and all the gold comes out.
01:57Music
02:02Guys, today is the 7th to 8th day.
02:04Earlier, our computer parts were like this.
02:08Here is the gold.
02:09And here is our gold which we are going to extract from these parts.
02:13You can see that all the gold that was on these computer parts,
02:17now it has become soluble in our solution.
02:20That is, it has come out of these plates and got mixed in it.
02:23Earlier it was something like this.
02:25Now it has come out of here and got mixed in the solution.
02:28You can see that all the metals that were on this plate have been collected along with the gold.
02:35Now what we do is, we take out all these computer parts and separate the solution.
02:41Music
02:43Now these parts, there is a little bit of gold in them, so we wash it with water and wash it and mix it in it.
02:50Then we will filter this whole solution with the help of a filter paper.
02:54Music
03:06Guys, you can see that all the gold that was on these parts has come out.
03:11Now there is no gold coating on it and it has come into our solution.
03:16Look carefully.
03:17Music
03:19This shiny thing that you can see, this is our gold and there is a lot of gold in it too.
03:25Now we filter all these things with the help of a filter paper and then we will make aqua resin.
03:30Guys, this is our simple filtration system.
03:33So let's filter it in it.
03:36So all the water that is there will come down and all our gold will be collected in it.
03:40Music
03:56Guys, today is the fourth day and finally we have filtered our gold with the help of a filter paper and dried it.
04:02But along with this, the glue on the PCB, the light plastic particles have also come into our mixture.
04:09So there is a lot of gold and a lot of garbage in it.
04:11So now it's time to make aqua resin.
04:14So guys, you know that the gold in aqua resin is soluble.
04:18So what will happen is that when we put this mixture in aqua resin, all the gold will melt in aqua resin, that is, it will be mixed.
04:24So this process of making aqua resin is a little dangerous.
04:28That's why safety first guys, because nitric acid and hydrochloric acid will be used in it, which is very dangerous.
04:37Because it is corrosive, it can burn your hand, it can blind you if it gets in your eye, it can burn your face if it gets on your face, that's why safety first.
04:43Guys, to make aqua resin, we will take three parts of hydrochloric acid and one part of nitric acid, that is, its ratio of acids will be 3 by 1.
04:53That is, if we take 150 ml of hydrochloric acid, we will take 50 ml of nitric acid.
04:59Please do not try this at your home, school or anywhere, it is very dangerous.
05:04Guys, you can see that we have prepared our aqua resin here.
05:13Guys, now let's mix our mixture in the aqua resin, but the gold particles are very thin.
05:20If I put this in it, a lot of gold particles will fly away, so I put the aqua resin directly in it.
05:25Guys, let's shake it a little so that all the gold particles start mixing in the aqua resin.
05:36It is exactly the same as when we put sugar in water and it mixes, in the same way, the gold will dissolve in the aqua resin.
05:44And after that, when we boil the water, the sugar is saved again, in the same way, we will separate the gold from it.
05:52We will not boil it here, we will put another chemical in it, which will separate the gold and the aqua resin.
06:09Guys, I think our gold has completely dissolved in the aqua resin, now it's time for its filtration.
06:15For this, we have prepared a filter paper and this is sugar paste, so that the plastic does not melt in front of the acid.
06:23And with the help of this, we have made a solution and now let's filter it.
06:27So, guys, what will happen in this process is that the gold is dissolved in the aqua resin, but all the other things are not dissolved, so all of them will be filtered.
06:48And the gold-dissolved aqua resin is coming down here, it has gold in it, the rest of the acid will be filtered here.
06:58Guys, now our solution has been filtered, you can see that a lot of acid has remained in this filter paper and we have found the gold under it.
07:09Now let's put another chemical in it, the name of that chemical is Sodium Metabisulphite, but before that, let's dilute this solution a little bit.
07:18Guys, now let's put Sodium Metabisulphite in this diluted solution, this will separate the gold, but this process is also dangerous because sulphur dioxide gas will come out of it, which is poisonous, you have to be a little careful.
07:33We will mix it very slowly, guys, you can see that the gold particles are slowly starting to accumulate in the bottom of the pan, let's put a little more.
07:49See guys, these black things are gold, let's put a little more, we will do it with a little patience.
07:58Guys, this process will take a long time, what will happen in this is that all the gold particles will separate from the aqua resin, after that we will filter the solution and separate the gold particles.
08:28This is a very long process, because until the reaction is complete, we will keep doing it with it.
08:41Guys, it's not that easy to remove gold, while removing gold, my gum was also opened.
08:46So guys, what we did in the last step, we put Sodium Metabisulphite and separated all the gold particles from the solution, and in the last step, we filtered the solution and separated the gold.
08:59Guys, what you are seeing, black, black, and what you are seeing in it, black and brinjal, this is actually gold.
09:06So now comes the next step, what we will do in the next step, the gold in this filter paper, the gold in this filter paper, now we will collect all the gold in one place and melt it so that we can get a solid piece of gold.
09:22But the difficulty in this is the crucible, the melting temperature of gold is very high, so the normal crucible in which we melt things does not work here, we tried to melt in this crucible with borax, but you can see that it is broken,
09:39you can see two dots, one is here and one is here, actually this is our gold, so now it was not working, after waiting for a month, we got this crucible, so maybe we can melt all these things in it and it will not break.
09:56Now the process of melting is also very important, because first of all we will heat this crucible a lot, then we will take borax and put borax on it, which will make a layer of borax on this crucible, so that our gold will not stick to the crucible and the gold will not oxidize in the atmosphere.
10:26Guys, we have melted one filter paper in it, now it will have to be melted more, first we have to melt all the papers in it, after that we have to put the crucible carefully, it should be on top.
10:56Guys, now all the gold has come in it, so now we will put more borax in it and melt it at a very high temperature, then the gold will be separated and the borax will be separated, I hope.
11:26Music
11:51Guys, the gold bowl is ready, now the biggest challenge is to take it out, as soon as it goes into the water, slowly, slowly, slowly, slowly, slowly, slowly, slowly.
12:13So guys, this is our gold bowl, let's take it out, this is the gold that we have recovered from PCBs.
12:30Yes guys, that's it, you thought it would be a kilo or two kilos, it was PCBs worth 14,000 rupees, and a lot of gold happens here and there during the process, but finally you can see that our process has worked so well that this is gold, we have got a small piece of gold here, tell you how much gold is there, oh wow, it is shining like gold, it is shining like gold, let's scratch it a little.
12:53Wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow, wow
