Copper mining in the United States Wikipedia
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s In 2017 the United States produced 127 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and PeruCopper was produced from 23 mines in the US Top copper producing states in 2014 were (inCopper Smelting Process The major producers of copper ore are Chile, USA and Australia, the vast majority of the ore coming from open pit mining In open pit mining the layers of soil and vegetation seam are scooped away until the copper bearing ore is exposed This is removed by blasting, the resulting ore collected and transported to the ore processing plantopen pit copper mining process gilhobbybe
Copper extraction Wikipedia
Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature The slag forming reaction is: FeO + SiO 2 → FeOSiO 2At this plant near Bingham Canyon, Utah, copper concentrate is turned into metal in a process called smelting Smelting heats up the concentrate at very high temperatures and removes most impurity elements Subsequently, iron and sulfur are removed in the conversion process The molten copper is then poured into moldsOpenpit copper mining, smelting, and production | Britannica

Smelting Wikipedia
Smelting is a process of applying heat to ore in order to extract a base metalIt is a form of extractive metallurgyIt is used to extract many metals from their ores, including silver, iron, copper, and other base metalsSmelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behindApr 24, 2017· The refining process for copper releases toxic gases and dust into the air Recycling reduces the emissions related to the mining and smelting According to KME, the Bureau of International Recycling reports that recycling copper saves 85 percent of the energy needed to produce new copperThe Advantages of Recycling Copper | Sciencing
