really cool video. everyone considering extraction of precious metals from HDD plates should watch this video first

I recover all values from HD platters/CDs/CD rom/Blue Ray with a profit! Removal of the metal coating on HD platters is done electrolytic, without any expensive acid, in a Hypochlorite Cell (free electricity from old used solar cells). The process takes less than 1 minute. The aluminium remains unaffected and is sold afterwards. Older HD platters indeed contain a bit of PMs, but newer ones contain very little. The Platinum layer is usually only around 10 nanometer thick. Most of the CDs contain a little Silver. However, for both HD platters and CDs the main yield is Nickel, which is worth 2½ times more than copper! The other metals are just an added bonus. Nickel is recovered by electrowinning. Afterwards, all liquid from the rest of the solution is distilled off (without any cost, utilizing the excess heat from my four pyrolysis units). The residue is stored until enough is accumulated for later recovery of primarily cobalt. Aside from Ni and Co, other metals present are Ti, Cr, and the more interesting ones: Ta, Ru, and Pt. Be aware that the small 2½" platters (from fx. lap-tops) are made of glass so they must be processed with acid. The consumption of acid is very minimal. The reason amateurs are misled to believe that no valuable metals can be found in HD platters and CDs, is that these metals are present in such a low concentration in the liquid that the primitive testing with stannous seems to show nothing at first glance. The color change is barely visible, or not visible at all, with the naked eye. You must concentrate the liquid solution to get a real indication. By the way, the green color of the solution (shown at the end of this video) is a clear visual indication that Nickel is present.

I'm pretty sure the platinum content depends entirely on the manufacturer.

Sir can you please create a video on recovery of pd and pt after you extracted the gold out of the material. Like tele boards? Thanks for your instructive contents.

Hi, just came across one of your videos, so I decided to check out your channel, seems how we share a similar hobby, or interest. I admit, I didn't have time to watch the whole video yet, but I wanted to ask you… Exactly what kind if “discs”, are being used in this video? Because they sure do not resemble any of the “disc” variations, that are available or accessible to the general public. I apologize in advance, if you have answered this question in the video itself, just wanted to be honest and hope you would be so kind as to tell me, til I have the opportunity to continue watching this video, and I am pretty sure I will find a few more worth watching! Thank you for your time and sharing your knowledge, to those who don't have the resources or support to do it themselves! I appreciate you!

I like his safety shoes though

Thanks.Lye will disolve the aluminum also.I thought they had pmgs .

Valid experiment. 🤝🏽

Gracias por tus videos

Checking with X-ray metal analyzer would be much informative, funny and easy. Then can be tried to extract smtg.

I don't have hardrives to collect (not many computers throughout my life). Its great information to know that Iron, Cobalt and Nickel are the metal coatings on harddisk platters. Someone says silver is in CDs and DVDs, though. I'll have to see how much. I do have CD music and many DVDs. If there becomes alot in grams of silver of probably owning 500+ DVD movies and 30+ music artists on CD I'll probably consider extracting maybe but most likely won't because I don't collect electronics for precious metals vs me saving the small amount of gold (in my like 10 old cellphones) and silver also in wherever they are said to be (like in contact switches).

Thanks guru ji

Excellent video thank you!!! Wish I would have seen this before wasting my acids!!! But you never know unless you test

I have seen the x-ray break down and all disk made after around 96 contain platinum and palladium and laptop ones go back even further,

Thanks for making video

Excellent

안녕하세요 잘 지내시나요? 후속영상 기다려집니다 🎉

👍🏻👍🏻👍🏻

رائع 👍🏾

Bu plakalarda kobalt madeni var, kobalt değerli bir element, bunun ayrıştırmasını yapmak mümkün mü?

Maestro,como se precipita el paladio con zinc? El acido nitrico hay que neutralizarlo o se pone directamente? Gracias

👏🏾👏🏾👏🏾👍🏾

Lanjutkan bos sampai jadi logam saya ingin tau apa jadinya itu bos

Ijin tanyak master..logam mulia apa yang terkandung didalam nya

I use a 2.5" plate for my cup of coffee 😊

Asombroso😳

Master

Bu beyaz altinmi paladyumu dostum

well that was a buzz kill.... but good to know! thank you

How often do you pour concentrated acid...while wearing Croc's?

Спасибо. Музыка бомба. Делай субтитры на русском.

Ahhh scarp I thought those disks were worth something.

2014 was the year of maximum Pt. Most platters after 2008 have Pt in the platters. Not worth the chemicals to recover....

Hello

Sar 500 ml Aqua regia naam

Well done mate about time the truth came out

Not platinum not paladium??? Rodium online! ?

❤😢😮😅😊🎉

Que tipo de disco son esos

এটা হলো কিছু!!!! Palladium বের করা শিখতে চাই 😭😭😭😭

Ciao questi disk sono platino giusto

Nothing's on it. I have tried it. Just wasted ur time😊

This video is for serving the masses, there's no real information here... This guy didn't recover anything!
