Copper minerals and other minerals are polymerized to form copper ore, and the copper ore that is mined out becomes a copper concentrate with a higher copper grade after beneficiation. In individual copper deposits, the content of copper can reach 3% to 5%. As early as in prehistoric times, people began to dig open-pit copper mines and use the obtained copper to make weapons, styles and other utensils. Copper alloys belong to the ranks of heavy metals. Most of the copper in nature exists as a compound or copper mineral. ‘Copper’ is left-shaped and right-sounded, Chinese pronunciation tóng.546 (64 for the calculation of secondary school) Copper is located in the fourth period of the periodic table, group IB.
Copper is a metal that exists in the earth’s crust and oceans.What is copper? Copper copper clad steel strips manufacturer is one of the earliest metals discovered by humans and one of the best pure metals. Copper heated in oxygen can react with oxygen to form copper oxide, but it is not a combustion, but rather a redox reaction.

Chinese name: copperChinese alias: copper, filamentous; copper, crumb; copper, granular; electrolytic copper foil; sponge copper; electrolytic copper; copper powder; copper yarn; nano copper English name: Copper Copper is the earliest metal used by humans . The content of copper in the earth’s crust is about 0. At the same time, copper is also one of the trace elements contained in the human body. Relative atomic mass of copper: 63.01%. The use of copper has a profound impact on the progress of early human civilization
