The heavy copper plates that have been shaped are called anodes. In the final extraction step—refining—any remaining minor impurities are removed from the anodes. The result is almost 100 percent pure copper. This metal will be sent to other plants to be made into products such as copper pipe and copper wire.

The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide, silica, and other compounds. Reaction in the flash smelting ...

Bottom-blowing copper smelting technology was initiated and developed in China in the 1990s. Injection of oxygen-enriched high-pressure gas strongly stirs the molten bath consisting of matte and slag. Rapid reaction at relatively lower temperatures and good adaptability of the feed materials are the main advantages of this technology. …

Of the many historically significant copper mining sites found throughout the Keweenaw Peninsula, the Quincy Smelter in Hancock, Michigan is one of the most complete. Built in 1898, the Quincy Smelter Complex is the best example of a 19th-century copper smelting operation left in the U.S., and possibly the world, featuring 17 buildings.

Image Source: Metallurgist. ... This stage of smelting produces matte or copper matte, a copper-enriched combination of copper, iron, and sulfur. The objective of the matte smelting step is to remove as much iron, sulfur, and gangue minerals (such as silica, magnesia, alumina, and limestone) as possible while reducing copper loss.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
