Studies re examine how major copper deposits form EARTH Magazine

The assumption [in the study] is that the processes going on in volcanic systems — in the shallow environment in volcanoes themselves — are somehow linked to the porphyry ore forming process says Jamie Wilkinson a geochemist at the Natural History Museum in London In reality he says many scientists think PCDs form when the arc

Processes that Concentrate Mineral Resources GSU

Processes that Concentrate Mineral Resources A number of processes occur in igneous rocks to provide accumulations of otherwise rare elements or minerals Most minerals are made up of the eight abundant elements and most surface minerals are silicates Our capacity to find the needle in the haystack of the metals such as gold silver etc comes from the fact that there are igneous

Geology of Copper Properties Mining and Formation of Copper

The deposits that contain the largest quantities of copper are called porphyry deposits and the process of extracting it usually involves drilling an open pit into a layer of sedimentary rock How Copper Forms in the Earth To understand how copper is formed it helps to look at how porphyry deposits—the largest current sources of copper ore—form
