Burnt Residue and Burnt Slag Processing Guide
Sandustry Burnt Residue guide for the gold chain: burn residue safely, plan for material loss, meter Kinetic Press input, and keep outputs clear.

Where does Burnt Residue come from?
Residue is produced whenever Wet Sand is processed by a Shaker. The supplied notes say it can be burned to create Burnt Residue, with some material consumed during that stage. This means the burn line needs room and should not be sized as if every input pixel survives.
Choose a controlled heat source
Manual fire is useful for testing, while an enclosed lava-based burner can provide continuous contact heat after it is built safely. Keep the burning area separated from sensitive belts, plants, and storage. Move only the intended Residue across the heat zone.
Meter the press input
Burnt Residue must then fall into a Kinetic Press with enough height and without mixed cargo. Use filters or a narrow feed to avoid several particles landing together. Leave a way to remove or recycle material that rests on top of the press.
Scale after the complete loop works
First verify the route from Shaker to burner to press to output. Adding more Shakers before the residue route is stable creates a larger cleanup problem. Increase capacity with parallel, isolated lines instead of one uncontrolled pile.
