In contrast to the symplectites that are due to infiltration and replacement,
examples are shown where symplectites are relics of replacement. Fig. 439
shows bomile (Cu2FeS4) as well as relics of bornite replacement by chalcopyrite
(CuFeS2).

The typical mineralogy of the Sweetwater bornite ores should produce
concentrates with about 60–61-wt% Cu if all of the bornite were to be recovered.
If the ores were 100-vol% bornite, ideal recoveries could reach 63-wtl% Cu. Even
those ...

In the second stage, the nonstoichiometric bornite was converted to chalcopyrite
on the disk surface. This is represented in the following reaction: Cu5_xFeS4 + (4
