Regard all the safety of the chemicals and do not do if you don't know what you are doing.

https://www.youtube.com/watch?v=TfIvwE75hvE It can be done but it not that efficient you may be able to get it as a cat converter (Maybe). Check out Canadian Chemist on heating and adding Nitric acid slowly 93 percent Nitric acid to HCl to dissolve and make Pt. Not much is made from all that 370 g Pt powder after extracting it tho.

You could use HCl and chlorine instead of Nitric acid but the small amounts of Pt may not be worth it in the Long run. You would need a big set up like 2 L flask reflux glass and slowly pump in chlorine into HCl. Nurdrage also told me electroplating Pt in HCl will release Chlorine. You would need an electroplating system 15 dollars that is resistant to Chlorine and HCl fumes. This is just an Idea to think of.

First, check whether it is worth the effort - hard drive platters contain roughly 2 milligrams of platinum, alloyed with other metals. You need to scrape off the 30 nanometre thick alloy layer, then chemically extract and purify the platinum.

Will the time you spend and the chemicals you buy be compensated by the value of the platinum you extract?

ummm there is no platinum in hd platters,

there is cobalt, nickle magnesium, aluminum, and phosphorus....

Yes there is a small amount of platinum along with a bit of rhodium which it adheres to.

mpilchfamily. you may want to double check your facts before you answer any more questions. the question was not do they have platnum . it was how do they harvest the platnum from them.

No they do not. If HDD had a small coating of platinum on them they would cost way more than they do now. If you want to find platinum then get your hands on some old catalytic converters from cars. They have a honey cone mesh in them with a small coating of platinum on it. But it takes some pretty harsh chemicals to get it off and filtered out. When all is said and done you're lucky if you can extract even a gram from them. The platinum layer is only microns thick. It's not really something you can do at home or worth doing at home.

How much do you think a couple milligrams of platinum goes for? It's freaking platinum not unobtanium!

Also catalytic converters have "palladium" in them. HDD platters do contain a small amount of platinum and another platinum group metal (possibly rhodium?) Because it is nearly impossible to get platinum to adhere to anything but a small number of similar metals.

That's why there's a big business stealing them..
And one enterprising street cleaning company has discovered that there is economically recoverable platinum in the crud they scrape out of the gutters.

ok... so.. someone explain the 2.2mgs (on average) that i recover from each platter disc.... granted thats only a quarter per hard drive 0.00 turned into 0.25 using maybe 0.015 cents of chemical then sold to refiner....
