Hey Tom, those metal brackets that the magnets are attached to are made from mu metal, a Nickel alloy that weakens magnetic forces. It shields the other components of the computer from the magnetic field. They are about 77-80% nickel and are heat treated in a hydrogen atmosphere to achieve a super high magnetic permeability. It should be possible to get a lot of nickel from them if you need it.

[@MabusParodies2nd]

I think this might be true for older hard drive magnets, and not anymore for newer ones. I have taken apart a lot of hard drives, and I've tested dozens of the brackets, and there was no nickel visible. Other people on the Sciencemadness forum tried the same and they couldn't recover any significant nickel, just iron.

I was doing this a while back, on the ScienceMadness forums. Hitting the magnets with a propane torch made it very easy to physically peel off the nickel plating. Dissolving and filtering a hot solution of magnets and sulfuric acid made it easy to separate the insoluble boron and flecks of missed nickel coating, but *some* does dissolve and will crash out when the solution cools as a very fluffy boric acid crystals. Once cleaned, this doesn't affect the rest of the process much. Once you have this filtered solution of Fe and Nd sulfates, this is further differentiated by heating to ~60*C to boil off water just until some of the Nd starts crystallizing out, then slowly cooling to

[@VoIcanoman]

I think another explanation for the different colours of precipitates of neodymium sulphate is crystal size and orientation. Research has been done in using both neodymium and samarium salts in paper money, to prevent counterfeiting, because the way the crystal structure is oriented with respect to the incident light source can apparently cause it to change colours. So slight changes in the overall distribution of crystals within a sample could bias the colour in one direction or another. I'm not actually sure if this is what's going on, but it is a known phenomenon.

[@argoneum]

Neodymium and iron somehow don't like to separate, what I did was adding some hydrogen peroxide to force the iron to form +3 hydroxide, then filter it. Still, took several repeats to get to any purity. Even when re-crystalizing by slow evaportaion there still was some iron left. Most of other lanthanide sulphates also have this reverse-solubility thing.

[@5467nick]

Iron and nickel should be easy to electroplate out of a sulfate solution while leaving neodymium in the solution. Electrolysis probably isn't often an answer to a chemistry problem, but it works great for something like this. I've electroplated iron, nickel, copper, and zinc with a variable voltage (0-32V), variable current-limit (0-5A) power supply I bought online for about $50 USD. I've even used it as a spot-welder for really thin metal foil and wires, for plenty of electronics projects, for charging batteries I couldn't find the right charger for, and just for making lots of sparks by shorting it on its max settings when I'm bored.

Actually, I was thinking he should've just secured the magnet in a vice, and just go at it with a bit of sandpaper. The nickel metal is likely far softer than the magnet it covers up, so it shouldn't be too difficult to just abrade it away while leaving the magnet untouched. However, Extractions & Ire is all about the struggle, about doing things in the most difficult and non-intuitive way imaginable, fighting against the very laws of physics and chemistry to eventually, maybe, achieve (usually just partial) success.

"My strength is not really one of my strengths" ... that had my in tears ... I got to use that at some point lol!

[@l0chj3ss]

What an awesome introductory video. This dude is great.

[@Enjoymentboy]

It's almost a drinking game hearing you say "neodynium" (with an N) over and over all while I can see the title of the video that clearly reads "noedyMium". But don't feel too badly. Most people over hear can't say aluminium properly. 😂

[@insouciantFox]

But Al didn't originally have the i, a la platinum; it was the Brits who decided to add the i for aesthetic purposes.

[@Paveway-chan]

This was such a riveting story! The bird had a character arc, the sulphate had a character arc, YOUR FACIAL HAIR has a character arc stretching years and years! Good stuff. You're worth your weight in gold y'know, because you're an Au-stralian chemist

[@tay-lore]

You and that momma bird are giving me lots of encouragement to finish the project that I've been working for way too long on. We can all do this!

[@mattymerr701]

You were defeated by some small screws, no wonder you struggled with the UV step

[@ExtractionsAndIre]

I’m not a quitter- but I am easily defeated haha. It’s a bad combination!

[@mattymerr701]

​@@ExtractionsAndIre I'm glad you didn't give up though. The content was worth the struggle

[@waltermalone2953]

I enjoyed the commentary from your Mum. :) I hope your family makes further appearances in the future. Great video!

[@PotooBurd]

I enjoy this so much! Amazing content, best wishes to you and your future projects! 🌻

[@TwitchFast]

The random conversation with your mother was icing on the cake lmao.

I think a hammer would be a good method to seperate the nickel plating from the ceramic core. The ceramic would crumble to sand, while the nickel would be malleable enough to turn into larger flakes. Then you can just seperate them with a sieve or some other mechanical method of seperation.

[@waxywabbit1247]

This is the way

[@R0bert811]

so many colors in this episode! Sorta missing Tar chemistry but crystals are cool too! You should try growing really big crystals

[@ttoctam3]

It's really self-affirming watching someone this smart melt a table that stupidly. You bring a comforting level of humanity to KZbin.

[@Mikkelltheimmortal]

I usually don't have anything to add to chemistry videos because I'm here to learn. But finally I have a piece of advice that's relevant. To get your magnets to dissolve better, heat them to red and drop it in cold water, next hit it with a hammer to make it shatter into pieces.

[@montikore]

I found this channel like 4 years ago and Tom is directly responsible for my new interest in chemistry. I'm not doing dick with it but I'm really interested lol

[@ChaosPootato]

Those crystals look reaaally nice

[@microTrash28]

I exposed myself to concentrated carbonyl fluoride for about 30 seconds. This is surely fine, never mind the intense burning of my lungs. Have a good one, mate!

[@tylernero6671]

I'm pretty sure computers feel pain, and you actually put them out of their misery of ever having to run an excel spreadsheet again

[@joshsickles1163]

I think hitting the magnets with a hammer would powder the magnet and leave the foil intact. Would make it the separation easier and make it so you can hit the computer with a hammer more.

[@benbevan3120]

My favourite video so far purely for the new lab partner

[@minikretz1]

Glad you left in the conversation with your mom, loved the concern and rambling about animals

[@Arbiter22J]

I have no background in chemistry but ive watched and re-watched your videos as they're so interesting. The best Educainment out there

[@rickyrico80]

Imagine thining Torx is some alien technology that takes a year to solve 🤣 We trust you bro 👌🏿

[@Ma_X64]

Hi, Tom. It's good to see how enthusiastic you are in what you're doing. I would love to participate in your experiments by making some equipment and automation. Unfortunately, I live quite far away.) But if you need some microcontroller based stuff then you can use something widely available like RP Pico and I'd be glad to help with its firmware so you'd just need to connect all the stuff together. By the way, you can dissolve the top Ni layer on the anode in sodium chloride solution. At least until it can be grabbed by its edge and ripped away mechanically. It's a very controllable process.

[@ExtractionsAndIre]

One day I would love to combine electronics and chemistry some more, make some custom machines that do some sort of chemistry or analysis. One day…

[@josephcoppernoll9547]

My favorite Australian chemboi playing with magnets, my favorite spooky magical science objects. What a time to be alive.

[@Jaymic]

Its crazy how Australian chemists use plastic cutlery for lab experiments and have live-in lab birds. Really goes to show how they do things different on the other side of the world.

[@laurahaaima1436]

They completely decompose in water after the protective layer is being exposed.. I was surprised to see how easy they fall apart in a day or 5

[@ElSuperNova23]

I swear you had a ball mill/rock tumbler at some point - just to get not-magnet powder first

[@switch2472]

Those crystals are beautiful. I love transition metal chemistry!

4:37 your hard drive is severely fragmented, the system has indicated it has filied 😂❤
