First it appears that water is getting under the stone and thus causing the
stone to oxide. I would first try to determine where the moisture is getting
under the stone and allow the stone to dry, perhaps even place a
dehumidifier in the area to assist in drying the floor. then apply a
poultice to remove the iron stains.,

I would open the floor with a 120 diamond to assist in the drying and then
apply the poultice using iron out. This may take several application to

Unless you stop the moisture from getting into the stone the oxidation is
going to occur again.  Be sure to seal after you remove all the stains.

Also the iron out is going to etch the stone so you will need to refinish
the stone.
