native copper and included utensils, tools, weapons, piping, ornaments, and jewelry. The largest deposit of native copper discovered to date was found in Michigan at the Keweenaw mines (Wood, 2001). Native Americans mined copper in this area between 5000 and 1200 BC, as evidenced by copper knives, arrows, spearheads, and axes.

Improving Copper Recovery from Production Slags by ...
With the existing process route in the pyrometallurgy of copper the recovery of valuable metals from the slag phase is not sufficient. The selective separation or enrichment of these metals into a metallic or matte phase would lead to an improved exploitation of the available potential. Beside economic reasons also ecological benefits would be given.

The crystals are shoveled with copper shovels into this hopper, which fills the pushcar underneath through a spout with slide in the center. As the tanks are 6 ft. deep, the crystals have to be thrown at least 7 ft. high, and in doing this work some of the crystals unavoidably fall back into the tank, frequently striking the shoveler.

In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation). The gas phase may also be used to advantage, either as a means of separating valuable volatile constituents or for removing unwanted volatile impurities. These separation techniques form the basis of thermal smelting and refining operations.
