average abundance of copper in ores

Abundance of elements in Earth's crust Wikipedia

The abundance of elements in Earth's crust is shown in tabulated form with the estimated crustal abundance for each chemical element shown as mg/kg, or parts per million (ppm) by mass (10,000 ppm = 1%).. Estimates of elemental abundance are difficult because (a) the composition of the upper and lower crust are quite different, and (b) the composition of the continental crust can vary

Copper Ore an overview ScienceDirect Topics

The copper ore production process operation as defined in Section 3.1 is simulated for a period of one year with various failure modes. The time evolution of the cumulative cost curves and copper output for 100 Monte Carlo (MC) simulations are shown in Figure 5 for easier visualisation. More MC simulations can be done while characterising the system.

69.17 % of the isotope with a mass of 62.940 amu will contribute to the overall average atomic mass of copper which is 63.546 amu. Since there are only two isotopes, we can assume that to complete the whole, 100% 69.17 % = 30.83% of copper's second isotope will contribute to the average atomic mass of copper which is 63.546 amu.

However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated. Copper minerals and ore are found throughout the Earth’s crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper

Geology of Copper Properties, Mining, and Formation of

2 天前· Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.
