Why are porphry copper deposits said to be large tonnage low grade deposits?
A large tonnage low grade mineral deposit that is porphyritic must mean that the desired ore is not substantial enough in the host rock to be economically feasible to extract. - Porphry copper deposits are said to be high tonnage low grade deposits as they tend to contain large amounts of rock with low (but still higher than normal) amounts of copper. Many of these deposits ARE economical to mine depending on other factors such as ease of processing, the association of other minerals such as gold, and geographic location with regards to infrastructure such as power generation and shipping (there are also many other factors that make mining operations viable). Cooper porphry deposits a very important sources of copper and, in some instances, are preferred by larger mining companies as they represent long term investments with predictable grade and limited processing challenges.
