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 in Michigan - Wikipedia

In the 1850s, mining began on stratiform native copper deposits in felsite-pebble conglomerates and in the upper zones of basalt lava flows (locally called amygdaloids).Although amygdaloid and conglomerate deposits tended to be lower-grade than the fissure deposits, they were much larger, and could be mined much more efficiently, with the ore blasted out, hoisted to the surface, and sent to ...
