Avi Oziel in: What are Tantalum Capacitors? How to recover Tantalum from Computers? 

Avi Oziel, thanks for the tip, I have some circuit board, and didn't know about this tantalum. thanks

He Identified a Electrolytic Capacitor as a Ceramic Capacitor.

To everyone out there just starting or to the experienced on gold recovery.There is a e-book called "THE URBAN VALLEY PROSPECTORS" How to reclaim gold from e-waste that is sold on amazon.it is a step by step walk thru of 5 different ways to reclaim gold from electronic e-waste useing simple every day at home chemicals and supplys. it is a very usefull and easy to follow e-book.and it explains everything needed to know to start you out and start reclaiming gold!!!!!!

You passed over two gold band crystal occilators. When you said what is that no that’s not one…. By weight they are great for gold recovery

What is the chemical procedure for recovering Tantalum. I really need this for a experiment in my college and I can't find any procedure i only see videos of gold and silver recovery

So I heard that the circular capacitors are t at tantalum only the oblong shaped ones contain it

One other thing - some of the Rockwell flatpack chips like the ones at 5:18 are a hybrid design and have a ceramic wafer inside the plastic with gold on it.

Also I forgot to mention the things you were calling monolithic ceramic capacitors, where Not. Mlcc are brown with silver soldering on each end. And on the board itself it will be marked with a "c" aside of it, if it's marked with any other letter then it's not a capacitor of any kind. Hope this all helps, I've gotten into Ewaste and I'm researching much info so I thought I'd take this time to share information for a change

Not all that is tantalum is yellow. There are also BLACK tantalum capacitors and mill spec cap's. Looks like little silver tube usually bent over on the board. Black ones look very similar to the MLC's.

At 1:40, you held up an aluminum electrolytic capacitor and called it a ceramic capacitor. I'm not even sure how you could confuse that because there is nothing ceramic in an electrolytic capacitor. Tantalum capacitors are also a type of electrolytic capacitor, which is why they can have much higher capacitance than non-polar capacitors. Also, at 5:29, you said all of the little boxes have palladium and platinum. The majority of them are resistors, not capacitors. Resistors are typically made of very cheap materials. There is some tantalum nitride or ruthenium oxide in some resistors, but you would be wasting your time and materials trying to extract those out of all the various SMT resistors found on circuit boards. At 10:05, you called the tantalum capacitors the power supply of the card and also said that the data is stored in there. The power comes from the power supply of the computer, quite obviously. The data is stored in the microchips. Electrolytic capacitors are very low quality capacitors, typically having a tolerance of 20%. Data storage has to be precise. The reasons tantalum capacitors are used are their size efficiency, low ESR, and high thermal tolerance. When you can't fit a tower-like aluminum capacitor on a circuit board, a tantalum capacitor is used. When minimum resistance is a requirement for a certain circuit, tantalum capacitors are used. When the circuit will have to tolerate temperatures that could almost boil water, tantalum capacitors are used. Besides that, great video. I liked the "Don't eat them" joke. I also love how you're learning about the various components of a circuit and how you encouraged viewers to learn about circuitry as well. If I were you, I'd scrap the inductors for the copper as well. Most inductors are cylinders that are shaped similarly to aluminum electrolytic capacitors but much shorter. They're a coil of copper around a magnetic bobbin, usually enclosed in a magnetic casing that's painted black. The casing can often be somewhat of a cube instead of a cylinder. Other inductors are the clearly seen rings with copper wire wound around them. Relays (usually large, black boxes with at least four pins) also contain an inductor that acts as an electromagnet. If you're going through the trouble to scrap the tantalum for $3 per pound, scrapping the copper from inductors and relays should seem like an easy, pretty penny.

Where are you selling the tantalum capacitors? What about the palladium? Where would you sell that? Crystal oscillators? I'm looking and not finding any info on who buys used or recovered components like these.

Yeah! What is that at 4:37?! I pulled a bunch of those of some boards. Is is gold plated around the edge?

Thanks for the great video, Avi. Do the Ta caps need to be carefully removed or just pulled/scraped from the boards? Just wanted to confirm it's the precious metals not the reusable aspect.

Hey do u think i can use your video in one of my videos im making later or tomorrow just to show my subscribers what tantalum is and what its worth??

I'm still struggling to identify Tantalum. I have 300lbs of boards out of old medical equipment from the late 80's and they seem to be covered in tantalum capacitors, I'm just not sure how to be sure about them. Some are skinny and long and some are the same old little boxes, not to mention others that look the same but in red, blue, and black.

The rarity and demand gives it (ta) it's high value. Gold is more plentiful but is in higher demand because of it's versatility and many more uses.

When I tried googling Ingredients to all of these capacitors and components, nothing would come up, Do you have a source for this information? AWESOME video thank you, a lot of good information!

Like most of the tantalum videos on RU-vid you are repeating some of the same misinformation. Tantalum is not worth more than gold and never will be! I can only assume you meant that tantalum caps are much more plentiful on a given board than gold-bearing parts, but your statement is misleading. Especially so after you just before that claimed tantalum is "rare" which obviously it is not. Pure tantalum metal may be worth in the range of $80/pound, but only a fraction of a capacitor's total weight is tantalum metal. Capacitors will have only 2 contacts. The 3 pin yellow device you pointed out at 5:58 is a Crystal as identified by the XT1 designation on the board next to it. The solder on it's leads may or may not contain some silver. The main difference there is that the crystal had to be soldered by hand and couldn't be flow-soldered like the rest of the board because of the way they chose to mount it inside a hole in the board. You'll note the blue electrolytic cap C14 right next to it is also mounted sitting in a hole to keep the board profile very thin, and it also has the same hand-soldered appearance. Also as a whole, tantalum capacitors do not mostly have a yellow color since there are so many types and shapes of tantalum caps. The yellow color is only most common for the surface mount variety. Last but not least I don't believe the "oval" component you showed at 2:15 is a tantalum cap at all, it appears to be either a varistor or more likely a ceramic dipped capacitor.

several of your social media links are out of date or broken

Sorry, did I miss how to cut away the individual Tantalum pieces???????????

Funny that i see this video just after i called it day sorting through stuff. I am about half way though sorting a 5 gallon bin i used to dump all the capacitors,oscillators,monolithic capacitors,pins,chips into while depopulating a weeks worth of boards. There really is a lot more worth on those boards then what some people are lead to believe. So much copper on the boards. I keep everything and anything that has a trace of gold on it,because it all goes into the chemical wash. By the way those silver looking little oblong things are called crystal oscillators. There is usually about 1 or 2 on each board,.sometimes up to 4..do collect them as well. Crystal oscillators have a small amount of silver and another metal in each them,be surprised how fast collecting so little soon accumulates up to a lot!. Thanks for the video Avi.

2 grams of gold is worth 80 dollars. So how is tantalum worth more for a whole pound of it?

the red brown one is called a dog bone and it has pure silver in it,

$80 a pound for tantalum compacitors vs. 1 oz gold is about $1300. How is tantalum worth more than gold?

I think you have some of your info mixed up for a few reasons... - that yellow thing with 3 legs is not a tantalum capacitor, tantalum capacitors only ever have 2legs/ends -there's also black tantalum block type capacitors - there's Also yellow and blue "stand up" capacitors, these type are always clearly marked for their positive and negative side -those yellow round "stand up" style capacitors you showed are Not tantalum, tantalum is shaped in more of a teardrop style not round

Avi Oziel in Gold Wars: How To Recover Tantalum Capacitors From Computers. In this video, Avi Oziel describe what a capacitor is and it's use on circuit boards and then compare the difference between ceramic and tantalum capacitors. I cannot stress how rare and valuable tantalum capacitors are and that they should be removed and set aside for its precious metal content is even more rare than gold. Tantalum is a very rare precious metal that is in high demand and on short supply worldwide. These little mustard colored capacitors should not be discarded as they they are worth $80 a pound.

Do some more reading and studying and try again

6:05 Is it really a capacitor? With 3 legs? I'm not sure, but it doesn't look like a capacitor to me. By the way tantalum capacitors may also be black. Here is the example : electropark.pl/3399-large/220uf-6-3v-kondensator-tantalowy-obudowa-c.jpg and ofc thanks for video.

what about the brownish ones, I was told they contain tantalum

You missed some of Tantalum Capacitors that are a black colored with positive mark on one end and old ones tant.cap. Please learn then educate others.

Avi , i been trying to contact you Check your Facebook messages , i did leave you there my number Cheers

on ebay it doesn't sell that well....

How is $80/lb worth "more than gold itself" when gold is $1k+/troy oz? Your math is way off.

Why didn't you show us how to take them off
