gold and sulfide minerals

I will say that from my understanding, many seem to agree that in sulfide gold ores, the occurrence of gold appears to occur as a replacement of other minerals, possibly iron. One USBM paper summed up five noticeable characteristics of auriferous pyritic ores. The gold occurs as tiny flakes on the crystallographic planes of the pyrite.

    In certain localities, minerals that contain these sulfides are heated high enough for the sulfides to dissolve, enabling the Gold to remain intact on the matrix. Such Gold is known as "Roasted Gold", and is occasionally sold to collectors. For additional information, see the gemstone section on Gold.

    Sulfide minerals Wikipedia

    The sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major anion.Some sulfide minerals are economically important as metal ores.The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts. Sulfide minerals are inorganic compounds.

    Sulfides are minerals that contain sulfur. These minerals are inorganic compounds, which means that they are formed through geological rather than biological processes. These minerals are commonly found in soils with a higher temperature. Oxides are those minerals that contain oxide anions, or oxygen, with ice and quartz being the exceptions.

    The source of platinum and palladium deposits is ultramafic rocks which have enough sulfur to form a sulfide mineral while the magma is still liquid. This sulfide mineral (usually pentlandite, pyrite, chalcopyrite or pyrrhotite) gains platinum by mixing with the bulk of the magma because platinum is chalcophile and is concentrated in sulfides.
