Ore Extraction & Refining

Calculate yields for any extraction recipe — pick the best machine, catalyst and tier — then reverse-refine: tell it how much Tungsteel, Steel or Cronite you want and it breaks the whole chain down to raw ore.

Extraction Calculator

Reference yields are per 10,000 units. Results scale proportionally to your input amount.

Refining Calculator (reverse — how much input you need)

Pick a refined metal and how much you want. This breaks the whole chain down to show exactly how much of every ingredient you need.
