It is also found with deposits of other metals, such as zinc, silver, copper, and gold. Lead is essentially a coproduct of zinc mining or a byproduct of copper and/or gold and silver mining. Complex ores are also the source of byproduct metals such as bismuth, antimony, silver, copper, and gold.
Refining. Most of the remaining impurities fall out of the copper sulfate solution and form a slime at the bottom of the tank. After about 915 days, the current is turned off and the cathodes are removed. The cathodes now weigh about 300 lb (136 kg) and are % pure copper.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
Copper in the Great Lakes. In the Great Lakes, the highest copper concentrations are found in Lake Superior, just offshore of the Keweenaw Peninsula, an area of prevalent historic copper mining. More than 500 million tons of copper mine tailings were dumped into .
Any metalbearing rock is known as ore. The feasibility of a mine is determined in part by ore grade. In the early 1900s, 30% pure ore (600 pounds of copper per ton) was the average copper content. By the 1930s, ore purity (concentration) had fallen to approximately 4%.
