The Art of Early Copper Tools

In Egypt, copper may have been the first metal used. The 12% copper content were extracted in the ores, and large selections of tools were formed including wood and stone. But, thanks to tempering, copper chisels and saws were used to work freshly quarried limestone from the 4th dynasty onwards.

Copper Mining and Extraction Sulfide Ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.

There has been little dispute over the last century that the primary copper sources that were exploited by the Old Copper Complex manufactures came from natural ore deposits spanning 120 miles along the southern shores of Lake Superior on the Keweenaw Peninsula. This native metal has an exceptional ratio of pure copper, typically over 95%.
