Atacamite in the oxide zone of copper deposits in
2006 11 28 Atacamite a copper hydroxychloride is an important constituent of supergene oxide zones of copper deposits in northern Chile whereas in similar deposits elsewhere it is rare In Chile it has generally been assumed to be a primary constituent of the supergene zones There are two difficulties with this supposition The first is that atacamite requires saline water for its formation

What is Copper Corrosion
2020 12 30 Corrosionpedia Explains Copper Corrosion Copper is considered to be a noble metal and as a result is able to resist attack by metal is basically immune to corrosion due to a naturally occurring protective film known as a patina that forms on the metal s surface If this protective film usually consisting of reddish brown cuprous oxide Cu 2 O is destroyed then copper will

What is an Oxidized Copper
2020 11 10 What Does Oxidized Copper Mean Oxidized copper is a specific type of corrosion that is produced during a three step process where copper oxidizes to copper oxide then to cuprous or cupric sulfide and finally to copper carbonate It results in a green colored copper layer or patina that forms over time. Oxidation is one form of metallic corrosion which is a reaction that occurs during an
