Thus much of the copper in the porphyry molybdenum system may be incorporated in early crystallizing phases. Hence later it is difficult to transport and deposit copper by late stage ore-forming fluids. In contrast to porphyry molybdenum deposits biotites from porphyry copper deposits record the relatively high Cl/F environment of formation.
The world& 39;s 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year about 40% of the world& 39;s total copper mine capacity. Chile and Peru alone account for more than half of the copper mines on this list. The U.S. makes the cut as well with two mines among the top 20. Copper is expensive to mine and refine.
