No Man's Sky: How to Get Chlorine

There are three main methods for getting Chlorine, other than just buying it from NPCs that is. These methods are as follows:

  • Refining - Chlorine can be refined from Salt.
  • Chlorine Farming - You can combine Chlorine with Salt to multiply your stocks.
  • Mining - Certain planets have Chlorine-based flora and minerals.

We'll now go into a bit more detail on each of these methods. Make sure you have a Medium Refiner, purchasable as a blueprint from the Anomaly. You'll also need a Terrain Manipulator, and ideally some upgrades boosting oxygen capacity while underwater.

Using a Refiner to turn Salt into Chlorine in No Man's Sky

Refining Chlorine From Salt

The best way to get Chlorine at first is to use a Refiner. Place Salt into it and add some fuel. You'll produce Chlorine. To get Salt, head underwater and look for Salt deposits in the form of certain minerals. Planets with large oceans often also have Salt listed in their available resources. You can find these using a scanner, then using a Terrain Manipulator to mine Salt Deposits.

Chlorine Farming Method

Once you have at least 100 Chlorine, build a Medium Refiner. You can then combine Chlorine with Oxygen to massively increase your Chlorine stocks. You can purchase Oxygen from Space Stations, or get it by using an Oxygen Atmosphere Harvester. With this method, you can make incredible amounts of Chlorine, which is actually a really great way to make money as well.

Mining Chlorine From Minerals

Finally, if you are on a planet that has Salt listed as a resource, you'll often find that certain minerals have Chlorine as a primary or secondary mining reward. Head underwater and scan minerals to see if the planet you're on has Chlorine embedded in its minerals.
