You don't. It's made in a cyclotron or reactor. It has no stable isotopes.
There are trace quantities in some radioactive ores, where it occurs as a decay product of other elements (for example, in pitchblende as a result of a the spontaneous fission of uranium).
The largest scale production of promethium ever on Earth was at Oak Ridge National Laboratory, where they could produce about 650 grams of it per year. That's a bit under a pound and a half.

What is the valency of promethium?
Promethium is an element and does not have a charge. As it has only be found in trace quantities, its chemistry has not been fully investigated. It has been anticipated that the likely charge when it forms compounds would be +3.
Is promethium malleable?
Yes. Promethium is a rare earth metal and is found in the periodic table in the Lanthanide section. Its symbol is Pm and it has the atomic number 61. It was predicted to exist, but could not be found in the earth's crust. Promethium has no stable isotopes, and what ones it has are relatively short-lived. It was first isolated from spent nuclear fuel, and later discovered in ores of uranium, but only in the most minute quantities.
What phase changes can happen to promethium?
Promethium can be melted and boiled.
What is the half life of promethium?
Promethium 145 has a half life of 17.7 years. Promethium 146 has a half life of 5.53 years. Promethium 147 has a half life of o.22 years.
How does promethium smell like?
Promethium does not occur naturally on earth, but as a by-product of uranium fission. It is very radioactive and its salts have a pinkish or reddish color. Promethium colors its surrounding air with a pale blue-green light.

Is Promethium magetic?
Promethium is paramagnetic.
How much promethium is produced and how much exists?
The world production of artificial promethium is 1-2 kg/year.The total mass of natural promethium in the Earth crust is under 1 kg.
Is promethium flammable?
Promethium is not flammbale.
What substances are in promethium bromide?
Promethium bromide contain promethium and bromine.
Is promethium flamable?

Is promethium soluble?
Promethium is not soluble in water.
Is promethium a solid?
Yes. Promethium is a solid.
Is promethium a flamable element?
Promethium is not flammable.
Do promethium have odor?
Promethium hasn't odor.
