Direct answer
Copper is a current Sandustry material. Copper comes from Copper Ore, a Filter can separate it when Ore is mixed with Sand, and a Smelter processes Copper into Liquid Copper. Build the chain so separation happens before the Smelter and each output remains visible.
Field note
Identify Copper Ore correctly
Use the current entity name and confirm the material at the source before routing it into a production line. Older snapshots that omit Copper are not reliable evidence against the current official page.
When Copper Ore and Sand share a flow, plan for separation rather than assuming the Smelter will ignore unwanted material.
Field note
Separate the mixed stream
Place a Filter where the mixed material can enter without burying the output. Keep the Copper path distinct from the Sand path and leave enough buffer to see which side is backing up.
Test a small stream before connecting storage or downstream machines. If the filter output is wrong, correct selection and orientation before increasing feed depth.
Field note
Smelt into Liquid Copper
Feed confirmed Copper into the Smelter and provide a destination appropriate for Liquid Copper. Check thermal and capacity conditions in the current build before treating the output as stable.

What this page does not claim
- Downstream recipes and Energy-chain values require current official or in-game confirmation.
- An older index snapshot incorrectly suggested Copper was absent; current official pages supersede it.
