17-10-2019· Porphyry Copper deposits play an important role in the global economy. These deposits provide over 60% of the world’s copper and include other important metals such as molybdenum, gold and silver. Porphyry copper deposits are known for their low grades and very high tonnage. A porphyry is not a rock type, but rock with a particular texture.
Copper Deposit is a resource block that can be found naturally on Resource Islands. 1 Obtaining 2 Usage 2.1 Drilling 3 Breaking 4 Trivia Copper Deposit naturally generate in island as part of Resource Island. Resource island appears every 18 - 24 hours in real life time. Copper Deposit can be mined to obtain 30 - 50 Copper Ores. Placing a Drill on top of Copper Deposit and fueling it with Coal ...
Geochemical exploration is an important part of copper-resource evaluation. A large number of geochemical exploration techniques, both proved and untried, are available to the geochemist to use in the search for new copper deposits. Analyses of whole-rock samples have been used in both regional and local geochemical exploration surveys in the search for copper.
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers 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. In later stages, circulating meteoric fluids may interact with the magmatic ...
