What happens when people die with metal in or on them?

The metal doesn't change. It's still there since it doesn't rely on the host living for existence.

By this point, Phase II will initiate as the metal bits reorganize themselves into a lining along your spine. They will take over control of your corpse for the following months, synthetically reanimating you. Nothing can stop your flesh from discolouring and rotting slowly, however. Eventually, the metal ennards will absolve themselves of your flesh vessel as it no longer suits their purposes, and control is returned to you once more; although your skin may by this point have discoloured into a shade of purple.

Before the human begins to decompose, the essence of the pacemaker leaves its plastic housing (the “accidental properties” of the device) and goes to a realm outside of space and time to forever keep the pace of the Great Heart for which it was ultimately created. The human, meanwhile, is eaten by worms.

So a pacemaker will keep going even if the person no longer has brain activity. So a strong magnet is swiped over the chest to turn it off. Not sure what they do with it after that, though

My grandfather died with a bullet in his foot that had been there for about 40 years. He was cremated and there was nothing left of the bullet.

Not a full answer, but some interesting info about metals and cremation https://collier-law.com/blog/cremation-what-happens-to-the-metals-in-your-body/

Where I live, removeable items like braces, jewellery, et cetera are considered 'personal effects' and will be handed over to next of kin when they claim the body for funeral arrangements. Integral things like fillings, artificial joints, etc. are generally left inside. There are cases where they have to be removed or will be left behind (eg. cremation), but they're still considered human remains and have to be disposed of properly.

There are also cases where things can't be cremated or left in the body. I'm thinking specifically about pacemakers powered by radioactive isotopes. Medical authorities will take charge of those.

What can corrode will corrode.

Gold or the peacemaker will not. They will only ever be destroyed / dissolved / ... in geological timescales. So when that part of the crust is pushed under another one. Or it is erroded away in a river. Or hot, geothermal water dissolves it. Etc.

Otherwise it will stay put and not change.

Humans from Scadrial who die with enough metal in them may become ghosts

Not reallly and answer, but there is a Stephen King short story and movie where a plane goes thru a time warp, and only the people who are asleep survive. The other people are gone entirely, except for the metal things they were wearing or had in them.

It's a good one!

It was the day my grandmother exploded.

We'll, if the peron had access to and chose, for their future postmortem body, to undergo the disposition option of 'natural organic reduction' (also known as terramation, also known as body composting), then Ive read and heard that: any implants that contain batteries or are highly radioactive (both likely or certain to also contain metal) will be removed early on, by a professional, for safety reasons.

Other metal(, like a metal hip, or bolts,), are typically left in the body, and stay jt thought the internment ceremony, (incidentally a future customer certainly can request that a particular song or playlist be played during their internment, , and several reportedly have opted for specifically metal (genre) music to be played at this point. 🎶),

and (continuing) any metal parts then go into the pod along with the wood chips and the straw and and oxygen and everything else, they stay with the rest of the bidy the 'beehive' through the first four weeks or thereabouts, and through the peak periods of intense heat.

Then, towards the latter stages, they are eventually screened removed, using a screen. similar to that used in many other conventional composting methods. Any metal prices are returned to friends or family of they wish to keep them, or otherwise they are recycled. ♻️

The final results of the process are tested by an independent lab, for a variety of factors. One of these is heavy metal content. The results must come back, as a legislative requirement, at a heavy metal cintkentbtahtad below a specified level, before the process can finish, and the terramated remains can be returned. So far there seems to have been no issue with being below the limit.

Anyway, that seems to be the process, for those that die with metal, and who choose to have their body sent to this particular funeral services provider. (recompose). For more on that you can red more at www.recompose.life , they have a faq section.

I belive it's a similar process for other providers of n. o. r services, and(in some ways) for some alkaline hydrolisys and cremation servjices.

maybe that helps answers the question, at least in some part.

They get a Viking funeral

Depends on whether or not they know Jesus. If they know Him they go to heaven.
