Abstract
Interesting chemical compositions have been
determined from the study of pyrite and chalcopyrite
samples from the active Buchim open pit mine. Namely,
beside the standard Fe, S, and Cu, increased
concentrations of gold and palladium always followed by
some amounts of arsenic were determined. In all the
analysed pyrites, gold concentrations were within the
range 0.027÷7.746% while the palladium concentrations
were within the range 0.010–6.784%. Gold
concentrations in all analysed chalcopyrites were within
the range 0.009–9.095% while the palladium
concentrations were within the range 0.020–8.110%. It is
evident that concentrations of gold and palladium in the
studied pyrite and chalcopyrite are almost always
accompanied by increased concentrations of arsenic in
the range of 0.002–0.761%. Increased gold and
palladium concentrations have been determined in
particular phases, especially in pyrite; in chalcopyrite they
are due to metal substitution in the mineral lattice.
