Buying sulfuric acid
Facts checked 1 Nov 2026
The next step dissolves your Weathered Olivine in Sulfuric Acid. You buy a working stock of acid once, about 2,000 tonnes, and in the lessons that follow you'll make it again and again from what the leaching gives back.
Why only 2,000 tonnes?
Leaching all your Weathered Olivine takes about 8,400 tonnes of acid in total. You don't need to buy all of that. Each round of leaching gives back Sulfur Dioxide, and the next lesson but one shows you how to turn it straight back into acid. So 2,000 tonnes, used four or five times over, is enough.
Buy it at Academy Market 2
The Academy sells Sulfuric Acid at cost at Academy Market 2. Buying works like selling, the other way round, and the same 1% fee applies, or 2% for a crew without a Merchant:
- Market Buy: Buy straight from the sell orders already waiting, at their prices. This is the one to use.
- Limit Buy: Name your own price and wait for a seller. Not needed here.
- Select Academy Market 2 and find Sulfuric Acid.
- Choose Market Buy.
- Choose your crew's warehouse as the destination, and about 2,000 tonnes as the amount. Check the total price in SWAY.
- Confirm, and approve in your wallet. The acid travels by hopper to your warehouse.
Look after your acid
Don't sell your acid while you still have leaching to do: it's the stock that keeps the loop turning. But it's also one of the most valuable things in your warehouse, so when your last round is done, sell what's left back to the Academy at Academy Market 2 before your hire ends. Anything left in the warehouse when the hire ends is cleared out, and its value is lost to you.
