You can do anything if you really want to.
The question is why would you really want to?
All the reactive metals require the electrolysis of molten salts.
Liquid metallic salts in an excess of 1500c then being subjected to a very high current.
Technical not that difficult but with extreme safety concerns that most domestic apparatus would find extremely hard to comply with.
Then we can address the scale issue, probably possible to produce some metal as proof of concept.
But the size of the reaction vessel and molten components to produce any notable quantity would necessitate a reaction vessel the size of a small house.
This proves ineffective if the reaction vessel needed to produce a notable quantity is greater than your original property.
 
Yes, magnesium dust (you can use shavings) perfectly precipitates gold from the solution. Much faster and better (in quantitative meaning) than zinc. If there are any other metals in your solution, all of them will be precipitated too. It can be used to rescue all your gold, silver and PGM-metals (except Ir) from almost any tainted solution.
Why will not Ir cement out?

This discussion is getting pointless :)
I can fly to Mars with Elon Musk, build a centrifuge, and enrich uranium if I need. Everything in the world rests on qualifications, cost, and limitations. And the obvious fact is that possible to obtain magnesium in small quantities under complex laboratory (!) conditions. But the author of the topic meant something else :) Therefore, the most adequate and short answer (not just to chat) to the question is NO. At home, not in a factory, obtaining magnesium in (a) reasonable quantity and (b) in reasonable ways, due to using which, without a license, you won't receive a huge fine, is impossible.

I would be rather impressed if you had the ability to set up Gas centrifuges at home.
Just a standardized centrifugal concentrator is quite beyond most home engineers.
It is the ability to distinguish
between that which we would find interesting to do and that which we should that separates two basic kinds of people.
 
Why will not Ir cement out?
There are many different reasons, enough for an article on chemistry :) Ir is the most difficult complex for precipitation among PGMs. But I think that few people will cope even with the quantitative dissolution of iridium into solution and its separation from platinum. In the former USSR, a native platinum 90/iridium 10 alloy without chemical treatment was often used.

I can, believe me :) Nearby, in an hour's walk, with me is the largest uranium enrichment plant in Europe :)

You said it would not cement out on Mg, which is strange since almost any metal you can think of would cement out on Mg.
That is the reason I asked.

Pt/Ir 90/10 is a "common" alloy in Jewelry making and such due to the inherent softness of Pt.

In almost ten years of refining, I have never come close to considering the recovery of Iridium or Rhodium.
It is all there, hopefully, cemented out on copper.
If it did not cement out on the copper hopefully the Iron cementation tank will have caught it.
The problem is most all services will only pay out on the larger recoverable metals.
E.G. will pay silver on silver chloride waste but will not even discuss the P.G.M. content after that.
Iridium, Rhodium, Osmium, and ruthenium are all such specialist chemistry only a few labs are set up to process them effectively.
They require very large entry lots beyond most all but the largest combined interest.

This is a "common" jewelry alloy because in most cases it is natural. Iridium is almost practically impossible to remove from Platinum. At least, taking into consideration just economic, not scientific reasons.

P. S. I mean receiving clear Iridium without Platinum and the fact that jewelers don't smelt Pt+Ir purposefully. Of course, Platinum approx. 999,5 can be refined separately (it is a much simpler process, but 0,005 of impurities are usually Ir)

Okay, then we need a new thread concerning the procurement and refinement of weapons-grade isotopes.
That may go against the forum rules in some places, I have a kind of inkling.
LOL
We are enriching NOT weapons, but uranium for fuel assemblies of nuclear power plants.

Traces of Iridium will be co-precipitated (well enough for AAS) with other PGMs, but that's all. I can try to point you to appropriate sources but in Russian:(
 
@Ultrax do you live near Zaphorizhzhia? Stay safe. Anyway now I'm curious to know what is the 0.5 % of my platinum half Eagle

Thanks :) I live a little further to the west beyond the Dnipro river, but less than 100 kilometers to the front line. We have a very "nice" weekend - mad Russian terrorists bombing our cities with Iranian drones and ballistic missiles :( So trying to stay alive :)

I know , I live in Italy and i would like to visit your country when this shit will be over. Tourism is going to be one of the multiple possible ways to help Ukraine economically. Great fan of Usyk and Lomachenko here. Sorry for the off-topic. Always interested to learn more about PGM
 
I love Italy :) An amazing country with centuries of history... I hope to visit Rome, Florence, and Milan :) I love Ennio Morricone's music, old Fellini's movies, and of course, Adriano Celentano's comedies and music :) Sorry for the offtopic too :)
