U.S. Copper Porphyry Mines Report - Earthworks

Copper porphyry is a form of copper deposit that is often characterized as low-grade typically with 0.4 and 1.0 concentration of copper and containing other minerals such as gold molybdenum and other trace elements in the ore body. Copper porphyry deposits are almost always mined in industrial-scale open pit operations.

Porphyry Copper Deposits | Geology for Investors

Oct 17 2019 Porphyry copper deposits are typically very-low grade with between 0.4 and 1 copper. The main mineral is chalcopyrite which is finely disseminated through the host porphyritic rocks. The only reason these ore bodies are economic is because porphyries are huge with hundreds of millions of tonnes available in a fairly low-cost mining setting.

Porphyry Deposits: The World's Largest Source of Copper ...

Oct 17 2019 Porphyry Copper deposits form along convergent plate margins or more specifically ancient subduction zones. As the dense oceanic crust becomes consumed by the mantle it begins to melt. This melting or “partial melting” of the crust creates magma that is less dense and begins to intrude into the overlying continental crust.
