Gold, diamonds, cobalt, copper and oil are major resources that are mined from the region; most mining is small scale, artisanal, and unregulated. Recently, mining groups have targeted coltan and cassiterite, rare minerals used in electronics such as mobile phones.
Copper is mined mostly in open pit mines, such as those found in Utah, New Mexico, and Chile. Chile produces the largest percentage of the world's copper with nearly 33% of the world's export. Copper is also found in the U.S., Indonesia, and Peru. Although copper has been used for thousands of years about 95% of all extracted copper was mined within the last hundred. In addition to the many mines found all over the world much of the copper we use has been recycled.
