Pure copper ore is a rare material found while prospecting copper deposits. pure copper ore is used in the creation of a few crafted weapons and armor. the ore its self is valuble to others who are trying to powerlevel their professions because it gives more experience than normal items.

Copper ore or cuprite is a common raw metal. it is used to create wires and appliances, such as generators. it occurs in the biome of sedimentary rocks along the edges of caves and reservoirs with medium veins. a block contains an average of 6501100 kg of copper ore. it is likely to be the first ore that your duplicants will mine.

A mk. 1 conveyor belt can move 60 resources per minute, so there is no point in setting up on a pure ore source before youve unlocked better conveyors. a mk. 2 belt can move 120, so it is ideal for pure sources. however, an iron or copper smelter at 100 can only utilize 30 ore per minute.

Copper ore does not contain pure copper, but either a coppersulphuriron compound chalcopyrite or a coppersulphur compound chalcocite. the metal must first be separated from such minerals by means of multistep metallurgic processes. in many cases these processes are so complicated that they account for up to 30 per cent of the metal price.
