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 1.27 million metric tonnes of copper, worth $8 billion, making it the world''s fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US.
Copper mining continued in the area until the Tennessee Chemical Company closed its mines in 1987 after 137 years of production (with only a 13year gap). In addition to the copper and other metals recovered from the Copper Basin''s ores, in the early twentieth century sulfuric acid was recovered from the smelter effluents.

Copper is one of the basic chemical elements. In its nearly pure state, copper is a reddishorange metal known for its high thermal and electrical conductivity. It is commonly used to produce a wide variety of products, including electrical wire, cooking pots and pans, pipes
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of lowgrade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper
The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper for this reason, leaching extraction is growing in importance.

Jun 25, 2019 · The world''s 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40 percent of the world''s total copper mine capacity. Chile and Peru, alone, account for about half of the copper mines on this list, but the U.S. does make the cut, with two mines among the top 20.
