The new classification scheme is multi-layered and allows classification of pyrite grains in different textural classes of increasing detail. The two main classes of pyrite occurring in Wits Basin reefs compose the first layer: 1) detrital (or allogenic) pyrite (Table 1), and 2) authigenic pyrite that formed in situ after deposition (Table 2).

We propose a revised, entirely descriptive classification scheme for detrital and authigenic pyrite in Archaean QPCs. The scheme was created in order to provide a consistent framework for the petrographic description of pyrite in clastic sedimentary rocks. Detrital pyrite is subdivided into massive, inclusion-bearing, and coarsely crystalline ...

How to Process Copper Ore: Beneficiation Methods and Equipment
Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

- Luster: Pyrite has a metallic luster, meaning it reflects light in a manner similar to a metal, giving it a shiny appearance.
- Transparency: Pyrite is generally opaque, meaning it does not transmit light and is not transparent.
- Diaphaneity: Pyrite is typically diaphanous, which means it does not allow light to pass through it.
Pyrite Mineral Data
Druse - Crystal growth in a cavity which results in numerous crystal tipped surfaces. Habit: Stalactitic - Shaped like pendant columns as stalactites or stalagmites (e.g. calcite). Habit: Striated - Parallel lines on crystal surface or cleavage face. Hardness: 6.5 - Pyrite. Luminescence: Non-fluorescent.
PYRITE (Iron Sulfide)
Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS 2, as marcasite; but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of clear indicators exists. Pyrite's structure is analogous to galena's structure with a formula of PbS.
Pyrite: The mineral pyrite information and pictures
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 …
Trace element variations of pyrite in orogenic gold deposits
A total of 4092 sets of pyrite trace element data were compiled from 67 deposits worldwide (Fig. 1).All the gold deposits selected have been unambiguously determined as orogenic type, covering the regions of the Central Asian Orogenic Belt (CAOB), Qinling Orogen, Jiangnan Orogen, the margin of North China Craton (NCC), …
Carbonate Classification
Embry has modified Dunham's classification and Klovan (1971) to include coarse grained carbonate s (above figure). In their revised scheme, a wackestone in which the grains are greater than 2mm in size is termed a floatstone and a coarse grainstone is called a rudstone. Both terms are extremely useful in description of limestone s.
