Test to see if it is rust-I would sand off using low grit sandpaper or electroplated pads 
Then reassess.

If it was me look at the finish.  If you don't know try like 220 adjust from there. if you see to flat go higher in grit 340 . If you need it less go 180 or 120 or 100. Hector Castillo

I have successfully removed dark spot from limestone by dry sanding.

 

It not un common for some limestone darken when they become too wet. In this case dry sanding has worked.

Maybe try sanding it out if it's just on the surface

Last week we cleaned limestone walls and floors for the residential customer  using our truck mount. We came back yesterday to seal the floor and were surprised by the look of one slab, with one continues stain at the bottom.  It lookes like iron oxidation and it is only 1 slab out of 6. We tried iron out but that didn't help. 
Any idea why something like that happened?
What can I use or do to remove it?
I am going back there on Thursday and I need your  help very badly. I am puzzled and without any ideas. I am attaching picture for u to see it.
Thanks
