The world is rich in copper resources. Copper is not difficult to extract from its ore, but exploitable mineral deposits are relatively rare. Some, such as the copper mine in Fallon, Sweden, have been a source of great wealth since the 13th century. One way to extract this metal is to bake sulfide ore and then separate its copper sulfate with water. After that, copper will precipitate on the surface of iron filings, and the formed thin layer is easy to separate. The proven copper in the world is about 350-570 million tons, of which porphyry copper accounts for about 76% of the total. In terms of regional distribution, there are five regions with the richest copper reserves in the world: < br / >
