WHERE & HOW TO FARM Where to farm A Nauvis uranium processing area supplied by acid-fed mining.
Process mined ore in centrifuges and route the isotope outputs separately. Ordinary processing produces both over time; buffer stock before relying on Kovarex enrichment, which needs accumulated isotope stock.
Before you go Uranium ore from powered drills supplied with sulfuric acid. Centrifuges and electricity. Separate routes and storage for U-235 and U-238. Establish acid-fed uranium mining and carry ore to the processing area. Configure centrifuges for uranium processing. Route U-235 and U-238 into separate stores or consumers. Check stock and decide whether fuel-cell or ammunition production is the immediate need. Keep ordinary processing running while required isotope reserves build. Start Kovarex only after its required stock is available and the process is researched. Monitor both stores and redirect output as demand changes. Farming tips Treat U-235 as stock to accumulate before enrichment, not an assured immediate supply. Keep U-238 available for recipes or enrichment that require it. Repeat, collect and use Ordinary processing repeats while ore and power are supplied; enrichment repeats when its requirements and inputs are met.
Common mistakes Starting Kovarex before enough U-235 is available; build the needed reserve first. Mixing isotopes in one store; keep outputs separate. Sending ore to a furnace; centrifuges are the processing step. When to stop or switch Pause enrichment if its stock needs conflict with other production; continue ordinary processing when more isotopes are needed.
