The best way to get the most prayer experience from your bones is to worship the Ectofuntus. You get four times (4x) the prayer experience per bone than you would if you had normally buried the bones. To do this, you must have started the Ghosts Ahoy Quest, though having completed the quest and having the Ectophial is a big plus.
After you have collected and banked a bunch of bones (Preferably Big Bones or higher), go to Port Phasmatys bank (Wear your ghost speak amulet to make banking faster) and collect 12 pots and 12 bones.
Go to the Ectofuntus tower, just north of Port Phasmatys (Using the Ectophial makes this quick and easy, if you have completed Ghosts Ahoy) and go upstairs.
Carefully right click on your bones and use it on the bone grinder. If you're not careful, you'll accidently bury the bones instead, getting normal prayer experience.
After you put the bones into the bone grinder, click on the bone grinder to wind it, then right click and empty the bone grinder. This will fill up one of your pots with Bonemeal.
Once you have all 12 bones ground and in the pots, go back to the bank and grab 12 buckets. Go back to the Ectofuntus tower again and this time go through the trap door to the west of the Ectofuntus. Work your way down to the bottom of the four levels, and fill your 12 buckets with Ectoplasm from the pool at the bottom. When you're done, go back to the main floor. (This would be a good time to use the Ectophial.)
Now you should have 12 pots of Bonemeal, and 12 buckets of Ectoplasm in your inventory. Just left click on the Ectofuntus to worship it. Each time you worship the Ectofuntus, one Bonemeal and one Ectoplasm will be used up. You won't be able to worship more than 12 times without collecting the ecto tokens from the Ghost Disciple. Once you are done and have collected your ecto tokens, go back to the bank, deposit the buckets, grab 12 more bones, and repeat the process.
Note: You can also buy Buckets of Ectoplasm at the Charter ship docks.
