Michigan

Copper mining in the Upper Peninsula boomed, and from 1845 until 1887 (when it was exceeded by Butte, Montana) the Michigan Copper Country was the nation's leading producer of copper. In most years from 1850 through 1881, Michigan produced more than three-quarters of the nation's copper, and in 1869 produced more than 95% of the country's copper.

How copper is made

In the United States, the first copper mine was opened in Branby, Connecticut, in 1705, followed by one in Lancaster, Pennsylvania, in 1732. Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of

Copper Handbook

8. Copper occurs in three different types of mineral-.zations - sulfides, carbonates and silicates. Sulfides are by far the most important and silicates are the least important. Sulfides consist of copper, sulfur and iron. Since copper metal is more easily extracted from the carbenate and sulfide minerals,

Anode Slimes

During the electrolysis process pure copper is deposited on cathode plates and impurities which are soluble fall to the bottom of the cell as anode slimes or sludge. Precious metals (Ag, Pt, Pd), can be extracted from the anode sludge created by the electro-refining process. Copper concentrates can also contain precious metals like gold and silver.
