How else could your turtle have lost the tip? If you think it's remotely possible that it was bit off by the other one, then I'd separate them. I'd still separate them to give the tip a chance to heal (the other turtle could be attracted by the scent of the open wound and try to bite it).
If you have any betadine, I'd dilute a little and wash the wound with that. Let it dry and apply some antibiotic ointment (Neosporin or Polysporin if you can't find the Neosporin). Keep your turtle out of the water a bit to give the ointment a chance to soak in. Keep the water clean so that the wound has less of a chance of getting infected.
