If harmonium is an alloy of lerasium and atrium, would it be possible to split the alloy into its respective metals some way?

I found this while looking into splitting alloys to see if actually splitting alloys is possible http://www.scienceforums.net/topic/58709-separating-alloys/

Brandon has addressed this. Basically, Preservation fiddled with the system so his 'sign of sixteen' would work and deliver the hint that he wanted people to see. This involved removing certain misting types so the numbers worked out.

Thanks for those hyperlinks btw they were very helpful.

Lerasium creates am incredibly strong Connection to Preservation which lets you access Preservation's magic system. All mistborn and mistings (other than through hemalurgy) are descended from the original rulers the lord ruler gave lerasium to as it's passed down hereditarily. Before TLR gave out lerasium beads mistborn were incredibly rare. Like in Southern Scadrial. 

As allomancy is of Preservation, not Ruin, Ruin's essence doesn't make you an allomancer even though the metal is allomantically useable. 

I’m still wondering though, why would you even even need to be a misting to use atium? Also if someone would ingest harmonium ( if it was possible) or even rayseium or tanavastium (or some other god metal for that matter), would they need to be a misting for that specific metal as well?

allomancy derives its power from Preservation.  Lerasium is a physical manifestation of Preservation's power.  Atium, however is a physicl manifestation of Ruin's power.  so in Preservation's magic system, Lerasium is sort of a key, granting access to it, while Atium is more restricted.  on the other hand, in Hemalurgy, which is more closely associated with Ruin, Atium is a universal spike, able to hold any attribute.  we don't know what lerasium does in hemalurgy, but it is probably more limited.

Thanks

Anyone can burn lerasium, while not everyone can burn atium. They're different that way.

Why should that be though, shouldn’t they have  the same amount of investability?

If Elend was able to use Lerasium without being a misting, that should mean that people could use Atium (or any god metal for that matter) without even becoming a misting. So when Preservation (aka Fuzz) affected 1/16th of the population, was that just to give them a hint as to what he was doing or did he actually need to make them into mistings? (Unless Elend was actually a Lerasium misting which destroys the whole question)
