Copper is a solid material extracted from Copper Ore.

The primary use for Copper is to melt it into Liquid Copper, through the use of the Smelter.

You cannot melt Copper with flames.

Because Sand and Copper Ore are often found together, you can use the same logistics to bring both materials to your factory, and then divide them with Filters for processing.

Smelting & Metal Casting Logistics

Copper Smelting, Mold Casting & Power Logistics Guide

Copper is the foundational conductive element for late-game power grids, wiring, and high-capacity battery banks. In Sandustry, Copper Ore cannot be melted by open flames—it strictly requires industrial processing inside an electric Smelter to produce inert Liquid Copper.

⚡ Quick Answer: How to Mine & Smelt Copper in Sandustry

Copper Ore spawns in deep underground caverns at depth 40+. It has higher hardness than standard terrain and cannot be melted by open flames or burners. Mine it with upgraded Drills or Void Gun pulses, separate raw ore from adjacent Sand with Filters, and pipe it directly into a powered Smelter to cast Liquid Copper into Copper Molds for 16-block loss-free battery storage.

Smelting Path: Copper Ore (Depth 40+) ➔ Filter Sorting (isolate Sand) ➔ Smelter ➔ Liquid Copper ➔ Copper Mold ➔ 16-Block Solid Battery

Refining Stage	Specification	Automation & Engineering Rule
Ore Extraction	Subterranean Pockets (Depth 40+)	Higher hardness than Dirt; requires upgraded Drills or Void Gun pulses.
Sorting Pipeline	Solid Ore Filter Sorting	Sand and Copper spawn adjacent. Route through mechanical Filters to avoid Smelter jams.
Smelter Refining	Smelter Furnace (No Flame Melting)	Flames deal zero damage to raw Copper. Feed directly into powered Smelters.
Liquid Mold Casting	Liquid Copper → Copper Molds	Liquid Copper is inert and non-freezable. Cast directly into Copper Molds for Battery cells.

💡 Pre-Smelter Filter Separation Rule

Because Sand and Copper Ore frequently intermingle in underground excavations, never pipe raw excavation output directly into your Smelter. Deploy a dual-way Advanced Filter Wall upstream: divert loose Sand into Shaker loops for Gold, and send pure Copper chunks into the Smelter furnace hopper.
