    Pyrite . The mineral pyrite, or iron pyrite, is an iron sulfide with the formula FeS 2. This mineral's metallic luster and pale brass-yellow hue have earned it the nickname fool's gold because of its resemblance to gold. The color has also led to the nicknames brass, brazzle and Brazil, primarily used to refer to pyrite found in coal.

    From Gold From Pyrites & Other Sulphides By E.H. HILL 1890: "Test for a Perfect Roast.—The object of roasting is to get rid of all the sulphur, arsenic, antimony, &c., that can be removed by the agency of heat, and to convert the iron, copper, &c., into oxides, thus freeing a portion of the gold and fitting the remainder for chlorination.

  • Geochemistry of hydrothermal gold deposits: A review

    Jul 01, 2011· The salinity and temperature of ore-forming fluids have wide ranges. Salinities of some ore-forming fluids are lower than sea water, whereas those in fluids forming porphyry deposits can reach 80 wt.% NaCl (Heinrich, 2007).The salinity and temperature of most hydrothermal fluid decrease during the late-stages of ore formation, suggesting either the attenuation of heat and fluid source or the

  • Copper-arsenic decoupling in an active geothermal system

    Over the past few decades several studies have reported that pyrite hosts appreciable amounts of trace elements which commonly occur forming complex zoning patterns within a single mineral grain. These chemical zonations in pyrite have been recognized in a variety of hydrothermal ore deposit types (e.g., porphyry Cu-Mo-Au, epithermal Au deposits, iron oxide–copper–gold, Carlin-type and
