Mar 28 2008 Copper in the Crust. The concentration of most metals is extremely low in Earths crust. For copper the most important ores globally are the porphyry deposits which form when copper and other metals are concentrated in fluids emanating from and flowing through shallow bodies of magma in the crust. Rapid cooling of these fluids or a sudden .
Jan 17 2013 Copper occurs in Earths crust average as 0.0058 by weight. as much as 96-99 of the mined material is left behind as tailings. More detailed Earths crust geology Britannica Online Encyclopedia
Apr 05 2012 Copper chains Study reveals Earths deep-seated hold on copper. Study of coppers behavior in arc magmas yields clues about potential location of new finds. HOUSTON April 5 2012 Earth is clingy when it comes to copper.
Copper is naturally present in the Earths crust at a concentration of about 67 parts per million. While most mines operate with copper concentrations of between 0.2 and 0.8 some of the richest ore bodies located in central to southern Africa can contain 56 copper.
Sep 04 2014 A Forecast Of When Well Run Out of Each Metal Here is one interpretation of when well run out of each metal or energy source. While the technicalities of some of this information can be debated I think the general theme runs the same. There is a
Copper minerals and ore are found throughout the Earths crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock.

Mar 11 2019 How Much Silver Is Left On Earth In The Ground It is estimated there was 530000 MT of silver reserves in 2018 Although silver was a principal product at several mines silver was primarily obtained as a byproduct from lead-zinc mines copper mines and gold mines
Because copper reacts readily with other substances it can be formed in a variety of ways in the Earths crust. It is often found in deposits with other metals such as lead zinc gold and silver. By far the largest amounts of copper are found in the crust in bodies known as porphyry copper deposits.

Copper is naturally present in the Earths crust. Global copper reserves are estimated at 870 million tonnes United States Geological Survey USGS 2020 and annual copper demand is 28 million tonnes. These copper resources are estimated to exceed 5000 million tonnes USGS 2014 amp 2017.
Jan 18 2016 The volume of the earth approximated as a sphere is 1086832411937 cubic kilometres. The calculated volume for the earth with 4km stripped off the top is 1084788886213 km 3. Subtracting the two and using the average abundance of 0.0031 ppm we arrive at 6.3 billion cubic meters of gold in the top 4km of the crust.
Extracting copper. Extracting copper. Picture 4. A copper mine. The size of the trucks in the picture give an idea of the scale. The copper ore has to be dug from the ground. The ore contains some copper mineral and lot of waste rock. The copper mine in picture 4 produces 6 tonnes of copper from every 1000 tonnes of ore.
Mar 22 2015 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 earths crust. I also showed why with the crustal abundance or the average crustal .
Copper is naturally present in the Earths crust. According to the United States Geological Survey Copper reserves amount to 870 million tonnes while resources could exceed 5000 million tonnes USGS 2020. It is widely anticipated that current and future exploration of copper will reveal an increase in both reserves and known resources.

The abundance of copper in the Earths crust is estimated to be about 70 parts per million. It ranks in the upper quarter among elements present in the Earths crust. Small amounts about 1 part per billion also occur in seawater. At one time it was not unusual to find copper lying on the ground. However this is no longer true.
