The Basic Refinery is similar to its larger counterpart the Refinery in that it refines Ores into Ingots. However, it is limited to only refining common metals: Iron Ore, Nickel Ore, Cobalt Ore, Magnesium Ore, Silicon Ore, Scrap Metal, and Stone. The Basic Refinery is 8x smaller, requires far fewer Components to build, and needs 41% less power to run. But it is also slower (65 % speed) and produces less usable material (Only 70 % efficiency) compared to the large Refinery.

However, unlike the larger and more expensive Refinery, it has no attachment ports allowing it to be upgraded. Unless you are short on space or resources, the Basic Refinery should be used as a stepping stone to constructing the larger and (depending on its upgrade modules) more efficient Refinery.

It has two inventory compartments: one that only accepts Ores (and Scrap Metal) and one that only holds Ingots. Both hold 4,000 L
4 m³
400 hL
by default.


Operating the Basic Refinery is similar to the Refinery. A simple example of its use is below:

Example Tutorial
  1. Build/place your Basic Refinery anywhere you like
    • If connected to a Conveyor Network, the furnace will automatically draw Ores from another inventory. However, for this example we will be placing the ores in manually.
  2. While close to the large conveyor port door; open the inventory.
  3. Drag your ore from your inventory on the left, and place inside the Basic Refinery. It will now begin processing automatically.

Based on game data file content.
Kilogram ore consumed per second = Ore Mass / (Ore RefineTime / Refinery Speed)
Kilogram ingots produced per second = Refined Mass / (Ore RefineTime / Refinery Speed) * Refinery Efficiency




Like the Survival Kit, the Basic Refinery can also refine stone into trace metals. It is much faster and happens automatically, but you get 30% less materials due to its Material Efficiency.
