"Native," or elemental copper can be found in nature, but most
copper is mined as oxide or sulfide minerals. Chalcopyrite
(CuFeS2) is one copper mineral that can be converted to
elemental copper in a series of chemical steps. Reacting
chalcopyrite with oxygen at high temperature produces a mixture of
copper sulfide and iron oxide. The iron oxide is separated from CuS
by reaction with sand (SiO2). CuS is converted to
Cu2S in the process and the Cu2S is burned in
air to produce Cu and SO2:
2CuFeS2 +3O2 → 2CuS + 2FeO + 2SO2
2FeO + 2SiO2 → 2FeSiO3
2CuS → Cu2S + S
Cu2S + S + 2O2 → 2Cu + 2SO2
How much chalcopyrite had be mined to produce 100 pennies if each reaction involving copper proceeded in 71.00 % yield?
