I got a bit lucky and bought a broken air dryer that had a big copper

Ugly!

The problem is that it is extremely heavily made and would not easily
cut with a cable cutter. I want to cut it up into pieces and clean to
make #1 copper.

Any idea what can cut it, maybe a circular saw with a small tooth
blade?

How long is the coil?

Not sure how long, it is very hard to unroll. I tried, as you see,
with big forklifts, but it was very difficult.

And what about the radial thickness?

Each tubing is over an inch thick, heavy, and inside this tube there
is a smaller tube, as this is a heat exchanger.

Do you have a portable bandsaw? That might bridge the radial
thickness. Are you cutting it in place, or can you bring it to your
place first?

It is at my place.

Maybe a low speed circular saw with a zero rake blade. Anything
with a rake will probably dig in. A pity the coil is not open enough to
use tubing cutters on it.

I bought a 60 tooth circular saw blade for "non-ferrous". I will give
it a try.
