  • Reasonable Pyrite Ore costs? - MMO-Champion

    2011-5-29  So take the price of 1 volatile earth, multiply it by 6.5, and if that number is between a third and half the price of a stack of pyrite, you're doing good. If its MORE than half the cost of the stack, buy those bad boys FAST. On my server earth is usually 6-8g each, and so when pyrite ore drops to around 85g a stack, its go-time.

  • The metamorphism of pyrite and pyritic ores: an

    Pyrite, the most widespread and abundant of sulphide minerals in the Earth's surficial rocks, commonly constitutes the primary opaque phase in ore deposits. Consequently, an understanding of the behaviour of pyrite and its relationships with coexisting phases during the metamorphism of pyritebearing rocks is vital to the interpretation of their genesis and post-depositional history.

  • Pyrite - an overview ScienceDirect Topics

    Pyrite (FeS 2) is commonly associated with other valuable metal sulfides, and with precious metals. In particular, some gold ore deposits contain the gold as particles embedded in grains of pyrite. In order to leach the gold, the pyrite must be roasted under controlled temperature and pO 2, such that only hematite (Fe 2 O 3) is present in the calcine. A sulfur–oxygen PSD for a metal provides a useful method of summarizing how a metal sulfide will behave as air is added to a reactor or

    2021-3-31  The unoxidized pyrite–gold ore type is the most abundant, and is composed of pyrite and rutile disseminated in fine-grained quartz. The unoxidized gold–copper ore, which comprises pyrite, enargite (in Kasuga) or luzonite (in Akeshi), covellite, scorodite, and rare native gold within a fine-grained quartz matrix, is found mainly in the upper section of the Akeshi deposit (Tokunaga 1954 ; Nakamura

    Finally, the characteristics of ore-forming fluids and evolution of the two types of deposits are determined via pyrite element surface scanning. This paper shows that micro-nanoscale study of gold-bearing pyrite is of great significance to understanding the gold mineralization process and is worth further study.

Since the stability limit of pyrite is 742 °C and no major break in the paragenetic sequence is observed, it is reasonable to conclude that pyrite deposition occurred between 665 and 742 °C. As quartz deposition did not occur during this paragenetic stage (Fig. 2), no fluid inclu-sion data or Ti in quartz temperature estimates are
