How much copper has been found in the world? | U.S ...

To date, roughly 700 million metric tons of copper have been produced around the world. This would fit into a cube measuring about 430 meters on a side.Identified deposits contain an estimated 2.1 billion metric tons of additional copper, which brings the total amount of discovered copper to 2.8 billion metric tons. This would fit into a cube measuring 680 meters on a side.

The ten highest-grade copper mines in the world

Well, grade is just another way of talking about the weight of copper. For example, if you mine 1 000 kilograms of rock, and 30 kilograms is made up of copper, then the average grade would be 3%. The global average grade of copper ores today is about 0.6% (meaning for every 1 000 kilograms of rock mined six kilograms will be copper).

9 Ore Deposits and Economic Minerals – Mineralogy

A mineral deposit is a place in Earth's crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse is not true.
