When I first booted up No Man’s Sky three years ago, I spent my first 10 hours of playtime hauling piles of raw iron and copper back to space stations just to scrape together enough units for a better exosuit storage upgrade. I had no clue that one simple tool would cut my resource grinding time in half almost instantly. Learning how to build a refiner in No Man’s Sky was the single biggest game-changer for my early gameplay, and it’s still one of the first tools I recommend every new player unlock as soon as possible.
What You Need to Gather Before Building Your First Refiner
The first refiner most players will get access to is the Portable Refiner, a compact version you can carry in your exosuit inventory and place anywhere in the galaxy. You don’t need a permanent base to use it, which makes it perfect for on-the-go exploration when you’re far from your home system. Before you can build one, you’ll need to gather a short list of common materials and unlock the base blueprint. You won’t need any rare resources for your first refiner, so you can pull all of these materials from the first planet you spawn on if you’re just starting out.
- 1 Metal Plating (crafted from 50 Ferrite Dust directly in your exosuit inventory crafting menu, no extra tools needed)
- 30 Oxygen (harvested from glowing red flora found on every habitable planet, or pulled from your life support system reserves if you’re in a pinch)
- 50 Ferrite Dust (mined from any standard rock formation using your terrain manipulator or multi-tool mining beam)
- Unlocked Portable Refiner blueprint (automatically unlocked during the opening tutorial, or available for 1 Salvaged Data at the Construction Research Terminal on the Space Anomaly if you skipped tutorial steps)
Salvaged Data is easy to find too: you can dig it up from glowing yellow data sites scattered across every planet using your terrain manipulator. You’ll only need one unit for the refiner blueprint, so you won’t have to spend more than 10 minutes hunting for it if you need to unlock it manually.
How to Build a Refiner in No Man’s Sky: Step-by-Step Placement Process
Once you have all your materials gathered, building and placing your refiner only takes a few seconds, even if you’re new to the game’s build menu. First, open your exosuit quick menu and navigate to the portable technology tab. You’ll see the Portable Refiner icon listed there if you’ve unlocked the blueprint. Select it, and you’ll enter placement mode.
When placing your refiner, always pick flat, clear terrain with no rocks, plants, or uneven ground in the immediate area. If you place it on a sloped surface or too close to another object, you’ll run into glitches where you can’t open the refiner interface, or it might disappear entirely if you walk too far away. That’s a frustrating bug I’ve run into dozens of times on mountainous planets, so I always take 10 extra seconds to flatten a small spot with my terrain manipulator before placing.
Once it’s placed, you’ll need to charge the refiner’s internal power supply before you can use it. The best fuel source for portable refiners is condensed carbon, which lasts four times longer than regular carbon and only takes two carbon to craft in your inventory. You can use regular carbon if you’re short on condensed, but you’ll have to recharge it far more often during bulk processing. Never use tritium, di-hydrogen, or other rare fuel sources for your refiner—carbon is abundant everywhere, so there’s no reason to waste valuable resources on power.
How to Use Your Refiner for Maximum Resource Value
Building your refiner is only half the battle: knowing what recipes to use will help you get the most out of every batch of resources you process. The portable refiner only supports one input and one output slot, but it’s still powerful enough to double the value of almost every raw resource you mine. For example, processing raw cobalt into ionized cobalt gives you twice as much product for the same input, and ionized cobalt sells for almost three times the price of raw cobalt at space station trade terminals.
If you’re out exploring and run low on launch fuel for your starship, you can use your refiner to make di-hydrogen jelly on the spot if you have di-hydrogen and carbon in your inventory. That’s saved me from being stranded on desolate frozen planets more times than I can count, especially when I’m exploring uncharted systems with no nearby space stations.
Once you build a permanent base, you’ll want to unlock medium and large refiners as soon as possible. Large refiners support three input slots, which lets you make rare high-value components like fusion igniters, stasis devices, and quantum processors that you can’t make with a portable refiner. They also process resources 50% faster than portable models, which makes bulk crafting for base building way less tedious. Refiner input ratios vary a lot between recipes, so always check the output preview before you start processing to make sure you’re getting the best possible return on your materials.
Common Refiner Mistakes to Avoid for New Players
I’ve made almost every possible refiner mistake in my 200+ hours of playing No Man’s Sky, so I can save you a lot of frustration by pointing out the most common pitfalls new players run into. First, never leave valuable resources in a portable refiner when you log off or travel to another system. Portable refiners are temporary objects, and they’ll despawn after about 15 minutes of you being away, along with any resources you left inside. I once lost 200 storm crystals worth 2.4 million units this way when I logged off to grab dinner, and I still haven’t gotten over it.
Another common mistake is only using your refiner for crafting base materials. A lot of new players don’t realize you can process almost every resource in the game to increase its trade value, even common stuff like ferrite dust and carbon. Processing 1000 ferrite dust into pure ferrite will net you almost twice as many units when you sell it, and it only takes a few minutes of processing time. That’s an easy way to make extra units early game when you’re saving up for a new starship.
Finally, don’t sleep on refiner recipes that use unwanted byproducts from mining. For example, the rusted metal you get from digging up old cargo crates can be processed into pure ferrite for free, instead of taking up space in your inventory. I used to throw all my rusted metal away until I found that recipe, and now I collect every crate I find just for the extra ferrite.
Learning how to build a refiner in No Man’s Sky is such a small, simple step, but it completely shifts how you interact with the game’s resource and crafting systems. It cuts down on grinding time, lets you make more units faster, and can even save you from being stranded on hostile planets when you’re far from home. I still keep a portable refiner in my exosuit quick slot even after unlocking multiple large refiners at my base, and I use it almost every time I go out exploring. Once you start using one, you’ll wonder how you ever played the game without it.
