There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide: 2 Cu2S(s)+3 O2(g)-2 Cu20(s)+2 SO2(g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide Cu20(s)C(s)-2Cu(s)+CO(g) Write the net chemical …Web
The whites first mined Lake Superior copper in 1771 in small quantities. In the early colonial days, the settlers used wood for fuel and charcoal for the forge and smelting works. Coal, however, was found in Rhode Island in 1768 and mined for use. The great bituminous seam near Pittsburgh, Pennsylvania, was struck in 1784.Web
The dates show that early Native Americans were among the first people in the world to mine metal and fashion it into tools. They also suggest a regional climate shift might help explain why, after thousands of years, the pioneering metallurgists abruptly stopped making most copper tools and largely returned to stone and bone implements.Web
First of all, copper very rarely occurs in its native metallic state.

The copper first exploited by prehis toric man was doubtless "native" copper, that is, the metal in a pure form rather than in the form of various ores. In many areas where rich copper-ore deposits exist it is quite easy to collect nuggets of native copper lying on the surface. Such supplies of the metal, however, are limited, and so the firstWeb
