There are two main types of copper ore found in the Earth's crust: copper oxide ores and copper sulfide ores. Copper sulfide ores (where copper is found in compounds with iron and sulfur) are the most common source of copper. Copper ore contains a low concentration of copper; around 0.5% to 2%, depending on where it is mined.
