  • Geology of Porphyry Copper Deposits

    As a mining interested learner, the geology of porphyry copper deposits is vital to your education. Now in the first Exploration Geology Course I discussed how because our current mining technology all the metals that we use are mined from the top 4 km of the earth’s crust.

  • Porphyry (geology) Wikipedia

    Collectively, these type of deposits are known as "porphyry copper deposits". Rhomb porphyry. Rhomb porphyry is a volcanic rock with gray-white large porphyritic rhomb-shaped phenocrysts embedded in a very fine-grained red-brown matrix. The composition of rhomb porphyry places it in the trachyte–latite classification of the QAPF diagram.

  • Porphyry copper deposit mineralogy Britannica

    Porphyry copper deposit, large body of rock, typically a porphyry of granitic to dioritic composition, that has been fractured on a fine scale and through which chalcopyrite and other copper minerals are disseminated. Porphyry copper deposits commonly contain hundreds of millions of metric tons of

  • What Investors Need to Know About Porphyry

    4-5-2019· Porphyry copper deposits are among the world’s most valuable deposits. Here’s what investors should know about them. Approximately 50-60 percent of the world’s copper, and 95 percent of molybdenum, comes from porphyry deposits. In the past, porphyry deposits

  • Porphyry Copper Deposits Geology for Investors

    23-7-2013· Most of the world’s copper is extracted from a type of mineral deposit called a “porphyry copper”. If you’ve seen a picture of a great big open-pit mining operation odds are that it was a porphyry copper deposit. Some of the biggest man-made holes in the ground are porphyry copper mines

  • Porphyry copper deposit Wikipedia

    The upper portions of porphyry copper deposits may be subjected to supergene enrichment. This involves the metals in the upper portion being dissolved and carried down to below the water table, where they precipitate. Porphyry copper deposits are typically mined by open-pit methods.

  • Exploration of Porphyry Copper Deposits

    So how do we explore for Porphyry Copper Deposits which are completely covered by barren younger rocks? Well let’s back up a bit, we know that porphyries form under large subduction related volcanoes and that most of these are located under the ring of fire around the subducting pacific plate another fertile subduction zone occurs in Balkans

  • Porphyry Copper Deposit Model USGS

    This report contains a revised descriptive model of porphyry copper deposits (PCDs), the world’s largest source (about 60 percent) and resource (about 65 percent) of copper and a major source of molybdenum, gold and silver.

    Therefore, porphyry Cu deposits are usually oxidized (with oxygen fugacities > ΔFMQ +2) (Mungall 2002; Sun et al. 2015). The problem is that while most of the magmas at convergent margins are highly oxidized, porphyry Cu deposits are very rare, suggesting that high oxygen fugacity alone is

  • What Makes for a Copper Porphyry Takeover

    16-11-2017· Major miners look to copper porphyry deposits for large-tonnage, low-cost operations. We take a look at what makes for a copper porphyry takeover target. Ask any economic geologist the most important factor in building a profitable mine and they will tell you “grade is king.” Grade refers to the

  • What is a Porphyry Copper Deposit?

    porphyry copper deposits were the first type of metallic mineral deposit to be exploited by large-scale, bulk tonnage, open pit mining methods. Economies of scale and advances in technology have made it possible to profitably mine these deposits despite their relatively low ore grades.

  • Gold in porphyry copper deposits: its abundance

    Porphyry copper deposits contain up to 100 t of gold and are among the largest reservoirs of gold in the upper crust (Kerrich et al., 2000). They are commonly surrounded by deposits and country rock containing gold that is thought to have been derived from them (Jones, 1992).

    In the porphyry-epithermal mineral system, pathways for fluids and their contained metals, ligands and sulfur include faults, stratigraphic aquifers and crystallising intrusive bodies. Crystallising intrusions are particularly important pathways for high-temperature, proximal deposits such as porphyry Cu-Au-Mo deposits and Cu-rich skarns.

  • Porphyry Copper Deposits Historical

    Fifty to seventy-five years ago, geologists such as Emmons, Locke, Lindgren, Sales, and Perry developed genetic concepts about porphyry copper deposits and their associated high-grade veins, breccias, and skarns which are still valid, such as their relations to granitic plutons and the evolutionary nature of their development.
