copper element

in the crust,Iron is the second most abundant metal element,second only to aluminum,and widely distributed on the ground,Leaving aside the technical problems of smelting, let alone aluminum, which was not solved until modern times,Iron was not the first in human history to be used as a metal rather than a mineral pigment,instead of copper。

There are two main reasons why copper was used earlier than iron.,One is that iron is easily oxidized,And the melting point is much higher than copper,Therefore, the technical requirements of iron smelting are higher than those of copper smelting.,Second, iron-bearing minerals do not market themselves as copper-bearing minerals do.,In nature,Iron-bearing minerals are mostly dull due to oxidation、color grey black,Most copper-bearing minerals have striking colors,either green malachite、Or blue azurite,Or the protagonist of today——golden chalcopyrite,It's too obvious to say that I'm here。

chalcopyrite


The main component of chalcopyrite is copper ferrous disulfide,Appearance with Pyrite(Ferrous sulfide)quite similar,So both have a dark history of being used as gold,and often symbiotically occur in hydrothermal sulfide metal veins,This makes it possible to distinguish between real gold,There will also be a situation where you need to tell which of the two fake golds is who.。

Pyrite


by contrast,The hardness of chalcopyrite is lower than that of pyrite,Mohs hardness is about3-4,Scratch with a knife,in addition,Chalcopyrite is often a massive aggregate,It is rare to see a single crystal as complete and obvious as pyrite。

The copper content of chalcopyrite is about34.6%,with the iron contained in it(about30.5%)、sulfur(about34.9%)There is a three-legged situation,But with malachite、Compared with most other copper-bearing minerals such as chalcocite,The copper content can be described as pitiful,despite this,It remains one of the most important copper-bearing minerals,The main reason is that chalcopyrite is widely distributed,Can be produced in many types of deposits:when exposed to the ground,Oxidized to form copper sulfate,Since copper sulfate is soluble in water,Malachite or azurite can be formed when encountering carbonate-containing aqueous solutions(Basic copper carbonate),in sulfide deposits,Its original composition will also be replaced to form chalcocite or bornite,in either case,can form a certain scale of secondary copper enrichment,Such as Tongling, Anhui、Dongchuan, Yunnan、Hubei Daye,They are all famous for their rich copper production.,Known as the Capital of Copper,important social、economy、Cultural and Historical Status。

That's all for this issue,Interested friends, see you next time!
