"Copper" redirects here. For the rock that copper ore is mined from, see Copper rock.
Copper ore is an ore which can be smelted in a furnace along with a piece of tin ore to create a bronze bar. Copper ore, along with tin ore, are the first ores a player can mine using the Mining skill, and requires level 1 Mining.
A player can smelt copper ore into a bronze bar through the Smithing skill by using it on a furnace along with a tin ore, granting 6.2 Smithing experience; this requires level 1 Smithing. Bronze bars can then be used on anvils to create bronzeitems, though some things may need more than 1 bar, such as a bronze battleaxe. Copper drops in the Al Kharid activity centre are common.
Beginners sometimes mistake copper ore as the unrefined form of a "copper bar"; this is not true.
