Copper Element Information Properties And Uses
The Earth formed from the same cloud of matter that formed the Sun but the planets acquired different compositions during the formation and evolution of the solar system. In turn the natural history of the Earth caused parts of this planet to have differing concentrations of the elements. The mass of the Earth is approximately 5.98times1024 kg. In bulk by mass it is composed mostly of iron 32.1 oxygen 30.1 silicon 15.1 magnesium 13.9 sulfur 2.9 nickel 1.8 calcium 1.5 and aluminum 1.4 with the remaining 1.2 consisting of trace amounts of other elements.

Gold In Porphyry Copper Deposits Its Abundance And Fate
Most metals are found as types of rock in the Earths crust. These ores contain sufficient minerals with important elements including metals that can be economically extracted from the rock. Metal ores are generally oxides sulfides silicates Table PageIndex1 or quotnativequot metals such as native copper that are not commonly concentrated in the Earths crust or quotnoblequot metals not usually forming compounds such as gold Figure PageIndex1. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals.

Next to chalcopyrite copper-glance is the most important ore of copper. It usually occurs in the upper part of the copperbearing lodes and is a secondary sulphide derived from the chalcopyrite met with at greater depths sometimes however the two minerals are found together in the same part of the lodes. The best crystals are from St Just St Ives and Redruth in Cornwall and from Bristol in Connecticut. Small crystals of recent formation are found on Roman bronze coins in the thermal springs at Bourbonne-les-Bains.

Copper-glance readily alters to other minerals such as malachite covellite melaconite and chalcopyrite. On the other hand it is found as pseudomorphs after chalcopyrite galena and organic structures such as wood copper-glance pseudomorphous after galena preserves the cleavage of the original mineral and is known as harrisite.
