U.S. Geological Survey Professional Paper
Most polished surfaces of the pyritic massive sulfide show small amounts of
sphalerite and chalcopyrite interstitial to the pyrite. Possibly some copper and
zinc were deposited with the pyritic massive sulfide, but the distribution of copper
(fig.
variations in organic sulphur may be fairly large. In low-sulphur coals the
variations in organic sulphur approach uniformity even for extensive areas. There
is no relation between organic and pyritic sulphur. High pyritic sulphur content in
a ...

Pyrite Oxidation and Its Control
It involved leaching pyrite or pyritic shale with a weak phosphate solution
containing hydrogen peroxide (H202). The latter oxidized a surface portion of
pyrite, released Fe"1 and formed an iron phosphate (FeP04) coating on pyrite.
Hydrogen ...
