CaF2 crystals in nature occur with such free F2. it is known as antozonite, or "stink stone" because when crushed the F2 reacts with O2 to form ozone

although its do-able, sounds like an extremely low yield procedure

unless you have access to a very intense source of ionizing radiation.
Toth et al produced fluorine directly by gamma radiation of a mixture of fluorides.
But they used a dose rate of 10E7-10E8 R/h
To put that into perspective: At 10E8 R/h it takes only 0.02 seconds to receive a lethal dose for humans.
But maybe if you mix coursely ground CaF2 with high grade uranium ore and let the mixture sit for a few years it may yield enough to be
noticeable/measurable. At least then you can claim having purposefully made F2.

A bit off-topic but I received an interesting email re. F2....
Hi Dan, FYI, I forgot if I mentioned that I found and purchased a cylinder of F2 gas diluted in Helium for an eximer laser to make fluorine element
ampules. Total net F2 gas content is 1.5Lbs or 15 Ft3 @ STP. I'm planning on cryogenically transferring the F2 gas to lecture bottles,minus helium,
which hold approx. 2 Ft3 at 2200 psig. so I need minimum of 8 bottles to completely empty the cylinder and I'd prefer to not fill the lecture bottle
to max. pressure for safety reasons, maybe half. So I have enough fluorine gas for a lifetime.
Absolutely terrifying and yet so attractive.

And a further email states that...
I only need a few bottles for my ampuling project so I'll have about a dozen of these [half-filled] lecture bottles left so
probably will offer some for sale to qualified buyers.
He expects that next summer is a likely time for this to occur. So, anybody feel qualified?

Qualified but not certified
btw, was this fluorine leftovers from SupaVillan's excimer laser? http://www.sciencemadness.org/talk/viewthread.php?tid=66635

Nice, wouldn't want to have it under my responsibility though.

This individual is a rocket technician, doesn't visit here. He's one of those guys handling (at one time) UDMH, RFNA, N2O2, MMH, and various military
high explosives. His testicles, I'm told, are Inconel. Former Edwards AFB guy, a real gem. One of the most amazing collectors I've ever met.
Qualified but not certified describes most of us with many of our projects, doesn't it?

Actually the reaction in that thread from K2NiF6 sounds interesting. Could this salt be produced by e.g. electrolysis of an HF solution of NiF2/KF?
