Most likely it is soldered in place in which case you will have to apply heat via a propane or oxy acetylene unit. Without actually seeing it that is the best I can do for you. Try "Ask A Handyman" if that is not a solution for you. Just put those two words in your search tool and voilà you will be there. They respond right away and be as specific as you can, remember that they cannot see it either.

Or chipping it out with a jack hammer had to do that be4

WRONG! It's not soldered in.
This is a cast iron flange secured by a lead and oakum poured and caulked joint. To remove a poured lead and oakum joint take a 3/8" drill bit and drill a few holes down past the lead and into the oakum.. Push a screwdriver under the lead ring and lever it up. Once it's free you can began to peel the lead ring out. Now pick out the oakum and you can pull the joint apart and remove the flange. Good luck, Tom

See you can learn a lot from this old man (talking about speedball)

I’m not a plumber myself, so I can’t say I have personal experience or anything, but I have a few friends who are plumbers, and all of them swear by the Flange-Out tool. It’s a drill attachment that makes removing a toilet flange a piece of cake. This is the website for it, in case you want to see it - http://www.flangekutsystems.com/ Like I said, I haven’t used it myself, but from what my plumber friends have told me, it works really, really well!
