Tell me about rare earth metals. Is there a way to mine/process them without polluting the environment?
Strictly non-political please.

>Is there a way to mine/process them without polluting the environment?
No.
>>8838188
yes
>>8838195
Really?
Can you explain how they are processed and what exactly in their processing causes pollution?
>>8838199
The processing doesn't matter. The mining process *will* create pollution and environmental damage. You can take steps to mitigate damage during the process and attempt to reclaim it afterwards; however, neither of those are entirely effective.

That's the best thing about asteroid mining, especially if we can also stick processing in space. Extraction of useful shit from the earth is always going to cause some kind of problem.
>>8838188
Maybe
everything we do on the earth causes some form of pollution.
you want pollution free rare earths? mine an asteroid of the moon.

Building rocketships to mine asteroids is a colossal waste of cash that only a billionaire could fantasize about.
>>8838299
More like a tetrillionaire or richer by a few orders of magnitude, but that doesn't mean that one of the best things about it is minimal to no damage to the environment where we live.

>modern electronics require rare earths, iridium, platinum group metals, and gold.

He obviously meant relatively speaking

if you can find a way to process the wastes for useful materials. then you can do it relatively pollution free.
the petroleum industry started just to refine kerosene out of oil, for lamps. then they dumped the rest down streams. Rockefeller of Standard Oil say the dumping as wasteful. because they could be selling that waste instead. So they found other useful hydrocarbons, like gasoline.

Not if you build the rocketships out of materials you mined from asteroids.

Dragon capsules have a large enough return to earth payload to make platinum, iridium, or certain rare earth metal mining profitable.
Just have to move the rocks into ISS orbit.

you fucked up.
