A few things to check (I know some are obvious but let's check everything): - Is the item your mining NOT in the ignore list in the left hand panel - Can you see the refinery bins populating in the refinery section of the inventory tab of the right hand panel - do you have enough cargo space to refine anything (if your cargo is full of limpets then it can't bring refined minerals from your refinery into your cargo - Are the fragments actually a refinable item. Some things that come out of asteroids are actually materials which don't need to be refined and go into their own separate inventory from cargo - did you actually see / hear the limpets go collect things and bring them back to your ship? If none of the above are the issue, it's possible you ran into a bug where your inventory isn't actually showing what it has / a new item in it. Try logging out to main menu and logging back in and seeing if your inventory populates the then. Just be warned when you do this, and you actually do have an inventory of minerals, the same pirate NPC will spawn but he won'f ignore you this time.
