Greatly Increase Prospecting Speed (Jewelcrafting) (Patreon)

1. Open the Jewelcrafting screen with a large amount of ore in your inventory.
2. Click Prospect, then Prospect All.
3. When a round of prospecting completes (ding sound and item appears in your bag), immediately click Prospect All again.

This will give you two lots of prospecting of ore from each of the two "prospect all" clicks you make, significantly reducing the processing time. As you might imagine the increase is about 100%. 

Obviously any activity which can be performed at twice normal speed is going to be twice as profitable.

This can cause problems with game stabilty  so you might not want to push this one too hard.
