My wife told me she wasn't interested in being extruded.

Here in East Texas we have a lot of iron and iron oxide in our sandy soil. I've used a magnetic sweeper to pick up iron pieces. It works really well.
I then used a propane torch to heat up the iron pieces (oxidized and not) to process it into non-oxidized iron. Needs much more heat than a torch to do it properly, but it did work.

Your idea can work, all the steps are doable. The actual procedure? Well that would have to be worked out.
