For the new craze in void opal or low temp diamond mining - where you're only looking for one resource, put a 1b or 1a refinery in a size 1 bay or a 2b or 2a refinery in a size 2 bay. If you're stuck with size 3 as your smallest available slot, put a 3a in it.

You might think you only need 1 bin if you're only mining one resource, however the bins act as cargo slots when you have no cargo space. If you carry on mining when your cargo is full, your refinery will continue to hold the raw materials until the cargo bay empties a bit. For example if after shields, fuel scoop etc you have available a size 2 and a 4 slot and you use a 4a refinery and a size 2 cargo bay, that's space for 10 + 4 = 14t of opals, but if you use a 2a refinery and a size 4 cargo bay, that's 6 + 16 = 22t of opals. That's 5million extra credits at the current inflated prices you can find.
