Copper is a soft, malleable, and ductile metal that exhibits excellent thermal and electrical conductivity. It is a popular choice for electrical wiring and electronic components due to its ability to efficiently conduct electricity and heat. Copper has a reddish-orange color and a metallic luster. The atomic number of copper is 29, and it has a density of 8.96 grams per cubic centimeter. Its melting point is 1,984ﾐ陳ｰF (1,085ﾐ陳ｰC), and its boiling point is 5,301ﾐ陳ｰF (2,927ﾐ陳ｰC). Copper is an abundant element and is typically found in the Earth's crust as copper sulfides and oxides. Copper is highly resistant to corrosion and can form a protective layer of copper oxide on its surface. This property makes copper suitable for use in various applications, including plumbing, roofing, and construction. Copper is also a vital nutrient for many living organisms and is essential for the proper functioning of enzymes in the human body. However, excessive copper intake can be harmful to human health, leading to copper toxicity. Copper has been used for thousands of years, with some of the earliest evidence of copper tools dating back to 5,500 BC. Ancient civilizations, such as the Egyptians and the Romans, used copper for coins, weapons, and jewelry. Today, copper is still widely used in various industries, including electronics, construction, transportation, and telecommunications. It is also used in the manufacturing of brass, bronze, and other alloys. In addition to its industrial applications, copper is also valued for its aesthetic qualities and is used in art and architecture. Copper's unique color and patina make it a popular choice for decorative pieces, such as sculptures and home decor. In conclusion, copper is a versatile metal with unique properties that make it valuable in various applications. Its high conductivity, resistance to corrosion, and aesthetic appeal make it a popular material for use in many industries. Despite its abundance, copper remains a valuable commodity and an essential element in modern society <a href=http://nopm.cc/>copper recycling</a> copper scrap metal

Copper porphyry: Large scale, low cost, long mine life
Copper, often referred to as ﾐｲﾐび咼r. Copperﾐｲﾐび� due to its predictive power for the global economy, has been on a steep upward trajectory this year. Over the past 12 months, copper is up more than 50%, surging from a pandemic low of $4,617 per metric ton in March 2020 to near-record highs of over $10,000 per metric ton in May 2021. The demand for copper, a key industrial metal used in construction, infrastructure development, and in the production of electric vehicles and renewable energy equipment, has been driven by the global economic recovery and massive infrastructure spending programs. China, the worldﾐｲﾐや┐s largest consumer of copper, has been leading this surge in demand. However, supply disruptions and bottlenecks have constrained the market, exacerbating the supply-demand imbalance. Copper output has been impacted by factors such as labor strikes, mining accidents, and COVID-19 restrictions. The COVID-19 pandemic also disrupted the supply chain, particularly the transportation of copper from mines to smelters and refineries. These supply challenges have created a perfect storm for copper prices, and some analysts believe that a great copper squeeze is coming for the global economy. A copper squeeze occurs when there is a sharp decline in copper stocks held in warehouses, which forces buyers to scramble for supplies and bid up prices. The current copper stocks held in warehouses, known as LME (London Metal Exchange) copper inventory, are at near-historic lows. Moreover, China, which consumes more than 50% of the worldﾐｲﾐや┐s copper, has been aggressively stockpiling copper over the past year to ensure its supply chain resilience. This has further tightened the market. The prospect of a copper squeeze has implications for the global economy. As copper is an essential input for many sectors, higher prices and supply disruptions can raise production costs, slow down economic growth, and cause inflation. Some sectors, such as electric vehicles and renewable energy, which rely heavily on copper, could face severe supply shortages. The copper marketﾐｲﾐや┐s dynamics are also closely watched by investors as they often reflect the broader economic trends and sentiment. The surge in copper prices is seen as an indicator of the strength of the global economic recovery and the shift towards green energy. In conclusion, the current surge in copper prices reflects a combination of strong demand, supply constraints, and stockpiling. The prospect of a copper squeeze could have far-reaching implications for the global economy, particularly for sectors that rely heavily on copper. As the world transitions towards a greener and more sustainable economy, the demand for copper is likely to continue to rise, making it a crucial commodity for future growth
