Which region of northern chile in south africa supports a very small population and is rich in deposit of copper and sodium nitrate

The Atacama desert is a cool, arid region in northern Chile.

It is a rich deposit of copper and other minerals.  The Escondida copper-gold-silver mine, located on the north of the desert, produces more copper than any other mine in the world.

This is also the world's largest natural supply of sodium nitrate.

explanation:

with the profits from the european sales, merchants purchased europe's manufactured  goods, including tools and weapons. then the merchants shipped those manufactured  goods, along with the  american  sugar and rum, to west africa where they were bartered for  slaves.

muslims have taken his goods and products to different parts of asia an indonesia. sometimes just traveled and trade, but in other occasions, stayed in the place and made a living.

trade was the key for muslims economies to prosper. their commerce routes reached far places like malaysia and java in the 11th century.

another important factor for prosperity was that muslim states served as the middle point for european traders.

they used to travel by land but sailing the seas -the indian ocean- really increase the exportation of products.
