Platinum is in Modern Hard Drive Platters 

Thank you for helping , or even leading the way on clearing the fog on the subject matters dealing with recovery of gold and all the other matters you cover sir.

Thanks for going to the trouble and expense and sharing the info.

Also... my scrap yard take those hard drive casing as extruded aluminum because, even though it is technically cast aluminum, they are of high grade aluminum and therefore allows me to include them with my extruded.

Lot's of people are scrapping hard drives but I suggest keeping modern H/D Platters aside for eventual Platinum recovery. Whilst we generally sell modern hard drives, in future, when we see lot's of 240gb+ drives going to scrap it may well be worth it. Keep Scrapping & Have Fun!

I look at it from a stacking standpoint. I'm already scrapping a hard drive, sell magnets, alum, sneak hardware into my #1 etc. It costs me nothing financially and very little space to stack platters until a backyard solution to recovery comes along. Minute traces of anything become significant when you are working with hundreds or thousands of units. Same reason I stack chips, mlcc, tc, compressor switches etc., eventually you end up with something. Love ya ben, keep up the good work, your videos have helped me immensely. Be well.

you are right about heat sinks and harddrive cases, i know a lad who casts pistons from it, he swears it is good stuff.

Bloody Electronics , keep doing videos and having fun ewaste Ben ! Papa's got a brand new bag !

Graet video Ben.I'm in one of my experiments, In my video I managed to recover a part of Platinum, although my procedure is not financially effective, the amount of Platinum I received was not worth losing Aluminum, but there are other methods that can save Aluminum and the Platinum at the same time. This is the procedure that one of my Subskryber left in a comment on my video: My method. Cut a grove in one edge of the platters to let the molten aluminum out and Rack the platters on a steel rack that looks like a swing set "A" frame above a graphite mold by about an 1". To catch the molten aluminum in a mold inside my Kiln that goes to 2000 degrees Fahrenheit. When the foils that are left are cold. I drop them in a bucket and cover them with Sodium Hypocholorite or bleach to get the rest of the aluminum out. Then wash with baking soda, dry and cut up and drop in a Whistler coffee pot and cover with Aqua Regia and slow boil till the chromium and PGM's dissolve. Then denature and drop. The aluminum recovery helps pay the electricity used and Solar with a Power wall helps too. My research indicated .005% Platinum per platter? Palladium can be used it wont magnetize. T.L Jenks is name this subskryber.Type a name on RU-vid, him profile will be first on list!!!,

Thanks for sharing Ben

You r so funny.. I love yor videos.. your a good teacher ❤️❤️❤️

Love your videos Ben.but this one gone over my head to technical for me 😂😂😂.and I'll give you a thumbs up every time great information

Would'nt the glasd ones be easier to refine than the aluminum platters?

Its worth it for me but I wait till i get at least 100 discs but you have all different sizes types I mix them all and always get between. 0.8 to 3.5 grams platinum per 150 discs approx. A third of a five gallon bucket. 95 percent plus purity

hello, great video again, thanx, 34:00 sometimes difficult to tell difference between aluminium and (stainless) steel, how to be sure?

Great video.

Why can you not melt down the glass platters all the heavy metals sink to the bottom?. Thanks for sharing

Another interesting vid, thanks Ben. I scrap all HD that come from homes and small businesses. If I buy a lot from the city, county or state, I test to see if they are useable because they are advertised with wiped HD's. Haven't resold anything yet.

You will find Platinum in perpendicular magnetic recording (PMR) disks. First introduced in 2005. There is not much, but the more data a disc can hold the more platinum it has in it.

I was wondering if you could leave a link to the "paperwork" that you kept fumbling thru the video? I would like to print it out and compare with the 40 some odd HDDs here with me.

I have a massive pile of platters but cant tell which ones were from 1905 or 2005

🤔it was interesting 😎 thanks for the information

Just FYI... For 2017... Tantalum per metric ton is $128,000 USD ($64.00~ USD lb). Not sure if that is recovered scrap tantalum or some other grade.

Codys lab tried a electron gun on a few and found none ?

Not all laptop hard drives are glass platters. I had several 80gb to 500gb drives that were aluminum.

what is the percentage of precious metals

Reader arms - some of them are made of magnesium as some laser untits in CD/DVD river are too. but I dunno in which models. As for HDDs I think that its very likely to find magnesium arms when the magnets are pretty small. So if ur in fireworks, just check them out!

@Ben will you show us how to recover the Platinum from the platters? (once you have a good amount)

are there specs from the companies that produce them ?

Can't remember the name of the alloy of the brackets that the neo magnets are glued to but it's loaded with nickel(about 50%).

I have a thought. What if you put the disc on a rotor. And then just shaved off the very top layer. Would this not include all the precious metals? At least the main one your after?

I also was wondering if you've had the chance to take apart any older computers/electronics. Do they contain higher percentage of precious metals? I figured they might considering electronics use to be WAY more expensive than they are today.

i did some math, assuming 20 nanometer thick layer of 33% platinum, at $1000 oz, the value of one 3.5 inch HD disc (the one you know it has Pt) worth 5.7 cents per disc, excluding values for cobalt and chromium

hello sir i have seagate 160 hdd pcb damgeD i cant found new one can i put 160 gb plates in seagate 250 gb for data recovery?

a wonder what 1 ton of platters would contain in terms of recoverable metals. cobalt and rhodium are worth quite alot.

Good info

Just subscribed, heard about you from other scrappers.

Interesting video

wana say HELOO from BOSNIA tnx on interesting videos .. long time folover , gg

It's not a calculation that I would know how to do myself, but surely with the data in that diagram, it could be possible to work out an average price per average platter in terms of precious metals. The atomic weight/size of the metal in question, multiplied by the total depth of the containing fraction, multiplied by the percentage of those metals in that fraction? Or something along those lines? Could help kickstart a HDD platter scrap price rise! What other purposes have people sold them for? I've sold for laser cutting art installations, I gather people can use them for scaring away animals from gardens and other artistic installations, any other audiences to target?

The boards are bigger on old ones but no platinum in the platers then new ones have tiny boards but platinum on the platers

Based on the spectroscopic thickness profile I did some calculations and the outcome was that 1 3.5" platter holds roughly 1 milligram of Platinum. In other words you need to process 1000 platters to get 1 gramm of Platinum (losses through process yield

I broke one this morning🤣 wish I would've seen this video beforehand

I haven't encountered a more thorough researcher who is a scrapper, anywhere. Benny, you have excelled yourself!! You might want to contact the platinum producers association in the USA to see if they have figures on how much platinum is sold into the hard-disk industry. They'll have figures but may or may not make them available to you. Can I get a copy of that chart somewhere or from you, please?

Yup the platters have rhodium plated platinum and cobalt on glass

Why don't U resale those hard drives , because most of the Laveno products come with out a hard drive Amazon is selling them for 30 or 40 and up to 119 , dollars

So u can even find gold in the ic of the hard drive cool.

Features of Platinum Element Slow expansion if exposed to heating. Slow melting in the water of fire We can distinguish between them through a test called zero test, which is a piece of white gold and scratched, if scratched easily is white gold, and the second method is to heat a piece of metal and let it cool until it turns to a dark color is white gold, It is a piece of platinum

Please make a video with you going through a whole board and explaining what every item is and what kind of metal it has

These layers are applied via ion deposition. This can deposit material only a couple atoms thick. No process used by a hobby scrapper will ever be viable. Now if you had thousands of platters and had access to a furnace where you could fractional melt, there may be a small profit.

With better hard drives, you can make more money selling them intact. I NEED some of the ones that you are smashing up to refurbish older computers. I need some of those to turn my old junk into functional units that I can pass on to people that can't afford to put out $900 for a working system.

I do not know where i read it, but because of the scarcity of them Rare Earth metals are taking a big leap money wise in the markets looking for them.

Really? i see some vids, wher guys say, there is no paladium and platinum in HDDs at all

Could have worn a glove when breaking that platter. I accidentally cut myself on the glass that broke one time.

👍👍

Love your videos man! But you could definitely shorten them up

Have you seen the video sreetips did on the glass platters, because he dosent agree

U cant gerneralize it that way. Ive seen aluminium platters in notebook drives and glass platters in large desktop drives. But how to examine aluminium or glass platters? take a magnet (strong Neodymium) and swipe over the surface, when the magnet tries to drag the plater with it while moving back and forth, its alu.

You should sell your screws x 10, make a mint.

Hey Ben. Great job. BUT you relly neede to scan this image and make a voiceover. Or include a URL for a scanned paper.... This is where dislikes are from (not from me, ofcause)

6 years later no one uses hard drive on their pc anymore

Ben, neodymium magnets come in different strength - some are well capable of drawing blood. Just check neodymium fail videos on RU-vid..

Ciao tutti i dischi sono platinum ciao

Watch videos from 2 reputable sources, one with aluminium discs and one with glass discs. Neither recorded any result worth pursuing.

This video was almost unbearable to watch. For gods sake man, just place the paper down on the table and let us read it while you talk and point with a screw driver or something!

For God's sake get to the point.

you talk to much and never get to the point uuuugh!
