How to Build a Continuous Copper Recycling Smelter

Setting Up the Hopper System

Recycling large quantities of copper blocks by hand can be slow, especially when clearing out builds with mixed oxidation and wax states. You can build a standard vanilla hopper system to automate the recycling flow.

1. Place a collection chest on the ground where you want your finished ingots stored.

2. Crouch and attach a hopper pointing directly into the back or bottom of the chest.

3. Place a furnace on top of that hopper.

4. Crouch and place a hopper into the side of the furnace for fuel, placing a fuel chest above it.

5. Crouch and place a final hopper on top of the furnace, topped with an input chest for your copper blocks.

Loading Mixed Copper

Open the top input chest and place any combination of copper blocks inside. Whether the blocks are waxed, unwaxed, pristine, or oxidized, the top hopper will automatically feed them into the furnace. The bottom hopper will pull the finished copper ingots down into your collection chest as each block finishes smelting.
