Copper Mining and Extraction Sulfide Ores

Copper is an unreactive metal it reacts only slowly with the atmosphere. This means that huge lumps of copper metal are found buried in the ground as nuggets. This is called native copper. The largest nugget of native copper ever found came from Minnesota USA and weighed over 400 tonnes. Native copper isn’t mined because there is so little of it. Therefore it is of little commercial ...

20.1 Metal Deposits – Physical Geology

Looking at copper for example we can see that while average rock has around 40 ppm parts per million of copper a grade of around 10000 ppm or 1% is necessary to make a viable copper deposit. In other words copper ore has about 250 times as much copper as typical rock. For the other elements in the list the concentration factors are much higher. For gold it’s 2000 times and for ...
