The metamorphism of pyrite and pyritic ores: an overview [PDF]
Mineralogical Magazine, 1993 AbstractPyrite, 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

The influence of pyrite content on the flotation of chalcopyrite/pyrite mixtures
Minerals Engineering, 2014In the flotation of copper ores, several processing plants report that copper recovery is affected by the proportion and reactivity of pyrite in the ore, with the effect becoming more intense when the feed particles are finer as a result of regrinding. In this work, a mixed model mineral system consisting of chalcopyrite (CuFeS2) and pyrite (FeS2) with

An XPS study of the oxidation of pyrite and pyrites in coal
Fuel, 1977Abstract X-ray Photoelectron Spectroscopy (XPS) was used to study mineral, synthetic and coal-associated pyrites, oxidized for various time intervals at low temperatures with humid air or oxygen. This was done to find out if XPS could detect, monitor and clarify pyrite surface-oxidative changes that influence surface-dependent coal-cleaning methods ...

A considerable variety of bacteria and similar microorganisms are present as preserved remains in pyrite samples of Pennsylvanian age obtained from the coal measures of southeastern Ohio. The types observed are similar to the present-day microflora found in stagnant pools of low oxygen and nutrient content.

Preparation of pyritized plant petrifactions: “a plea for pyrite”
Review of Palaeobotany and Palynology, 1973Abstract The opacity and difficulty in preparation and microscopical examination of pyrite and marcasite petrifactions tend to discourage many workers. In recent years, however, techniques have been developed to help the paleobotanist prepare and study these petrifactions.

Pyrite-chlorite and pyrite-biotite relations in sandstones
Sedimentary Geology, 1986Abstract Authigenic euhedral pyrite in feldspathic sandstones of the Visingso Group (Upper Proterozoic, southern Sweden) is observed to be closely associated with authigenic, fine-crystalline, interstitial chlorite and/or sand-sized chlorite or biotite. Microprobe analyses revealed that chlorites which are accompanied by relatively large amounts (≤ -
