Description
The Morenci mine is a “porphyry copper deposit” in Arizona that has been in production for decades and is the largest copper producer in North America. Besides copper and Azurite, minerals such as Malachite, Chrysocolla, Hematite, Tenorite, Cuprite and others are found during the mining process and recovered for collectors.
“Porphyry copper deposits” are copper ore bodies that are formed from hydrothermal fluids that originate from a large magma chamber below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name.orphyry copper deposits are currently the largest source of copper ore.
Porphyry copper deposits are currently the largest source of copper ore and are typically mined by open-pit methods.
