of the host Ordovician turbidites. In contrast, wall-rock-hosted disseminated, fine-grained auriferous pyrite–arsenopyrite mineralisation at Fosterville post-dated both the development of chevron-shaped upright folds and fold-related faults and the emplacement of Early to Middle Devonian felsic dykes.

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.

within fine-grained sulfides (pyrite and chalcopyrite). Evidently, the precipitation of gold was an integral part of the hydrothermal alteration system and was associated with sulfide minerals. Although electron microprobe analyses of auriferous sulfide indicated the presence of gold in sufficient quantities to explain
Much of the massive pyrite in the veins of Colorado, California and of the southern states, from ia to Alabama, is auriferous and is mined for the gold it contains. Gold is separated from the pyrite partly by crushing and amalgamation and partly by smelting or by leaching processes.
Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...
The auriferous pyrite is mainly allotriomorphic and homogeneous in chemistry with a homogenous distribution of As, Ni, Mo and Fe from the core to rim of grains. These features are consistent with ...
Abstract. The authors propose the process for selective flotation of auriferous pyrite and arsenopyrite, where the combination of xanthate, 2-hydroxylpropyl ester of diethyldithiocarbamate acid (HPEDEDCA) and oak-bark extract (OBE) is used to produce pyrite concentrate recovered into the froth product.

Abstract. Large rounded pyrite grains (>1 mm), commonly referred to as "buckshot" pyrite grains, are a characteristic feature of the auriferous conglomerates (reefs) in the Witwatersrand and Ventersdorp supergroups, Kaapvaal Craton, South Africa.

Pyrite is the most significant source of oxidized sulphur and indirectly, hydrogen ions, in a sulphide. An oxidized ore is defined as one in which the ore material has been oxidized or weathered, possibly in a zone that is atypical of the primary sulphide deposit, and for which some especial processing may be required bearing rock volume ...
