When a smelting process produces a byproduct, collect it as a separate material stream so it does not obstruct ingot handling. The byproduct’s usefulness depends on the process and the needs of your current factory.

WHERE & HOW TO FARM
Where to farm
At a smelting machine whose active process displays a byproduct output, with room nearby for separate storage or a confirmed accepting consumer.
Use this guide to turn an observed secondary smelting output into a collectible stockpile or an accepted downstream input. Check the active process first: not every process is established to produce a byproduct, and available uses can vary with the build.
A smelting machine and an active process that displays a byproduct
Ore and the fuel or power required by that process
A separate accessible receiver for the byproduct
A downstream consumer only if the current build shows a valid use for that material
Inspect the active smelting process and identify each displayed output, including any byproduct.
Run a small operating batch and observe where the byproduct appears at the machine.
Place or designate a separate receiver for that material so it is not confused with ingots.
Connect the byproduct output to its receiver using the logistics available in your build.
Check that the receiver accepts the material and that it does not fill before the ingot route does.
If an available machine accepts the byproduct, connect the stored output to that consumer and verify that it is used.
Keep the receiver accessible and collect its contents for storage or processing when capacity is needed.
Farming tips
Use the process interface to confirm outputs before building a dedicated byproduct line.
Keep byproduct storage separate and labeled; this makes its stock visible and prevents accidental mixing with ingots.
Repeat, collect and use
This collection loop repeats while the selected smelting process runs and continues producing the displayed byproduct: receive it, store it, then move it to a confirmed consumer or retain it in storage. If the process produces no byproduct, there is nothing to collect.
Common mistakes
Assuming every smelting process produces the same secondary material: check the active process’s outputs.
Sending byproduct into an ingot receiver: give distinct outputs separate receiving space.
Connecting it to an unverified consumer: confirm the machine accepts that material before relying on the route.
When to stop or switch
Stop collecting from this line when the process changes or the receiver has no room. Resume after confirming the output and restoring storage or consumer capacity.
