Copper Ore is an early game ore, which spawns on the surface as well as in the Underground and Cavern biomes. It is the weakest and most easily obtained tier of ore in the game. Its primary use is to make Copper Bars, which can be used to create the Copper tier of equipment.

Economics determine whether a mineral ore deposit is valuable enough for excavation. The components needed for processing are then extracted from the mineral aggregates that have been mined. Various steps are necessary – mixing, grinding, etc. – for the processing of natural materials.

Copper can be found as a metal in the ground. Normally, it is green on the outside. Most copper is not as a metal but in chemical compounds. Chalcopyrite is the most common copper ore. It is a mixture of pyrite and copper sulfide. Copper is found in small amounts in living things.
