Chalcopyrite recovery and pyrite recovery as a function of water recovery (a) and Cu grade of flotation concentrates as a function of chalcopyrite recovery (b) in the flotation of chalcopyrite against pyrite in mixed mineral systems using fresh water (FW, solid points) and seawater (SW, hollow points) at pH 8.5.
Sodium Metabisulfite MBS for pH Control and Pyrite
Sodium Metabisulfite aka MBS is used for pH control in froth flotation to control Pyrite depression. Below is a graph showing pH VS pyrite recovery at various collector addition rates. It is also used to prevent flotation of sphalerite by copper activation in the presence of Tennantite/Covellite in the ore. For pyrite flotation, you see maximum iron/pyrite depression using Sodium Metabisulfite

Mar 31, 2015 · Acid mine drainage (AMD) refers to the outflow of acidic water from coal or metal mines, often abandoned ones where ore or coal mining activities have exposed rocks containing the sulphurbearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this compound forms a dilute acid, which can wash into nearby rivers

Role of pH and dissolved mineral species in Pittsburgh No
The role of pH and of dissolved mineral species on the separation of pyrite and non flotation process currently used in coal preparation plants is a relatively crude process (Osborne, 1988), not being capable of rejecting pyrite to the desirable water or in caustic solution) the 1/4
Pyrite Pyrite (iron disulfide), known popularly as fool''s gold, is a common mineral in the Piedmont and occurs in metamorphic, igneous, and sedimentary rocks. Pyrite deposits in the Hillabee Greenstone geologic formation in the vicinity of Pyriton, Clay County, were first mined in the 1850s by mining companies for the production of sulphur acid

Pyrite: The mineral pyrite information and pictures
The Mineral pyrite Pyrite is sometimes called Fools Gold because of its similarity in color and shape to Gold. In the old mining days, Pyrite was sometimes mistaken for Gold, as they frequently occur together, although Gold and Pyrite can very easily be distinguished by simple observation and testing of characteristics.
When these nodules are split open, the fossil appears as a 3D external cast and mold. Mold surfaces may be coated with kaolinite, pyrite, calcite or sphalerite. Plant material is sometimes covered with a carbonaceous film (Nudds & Selden, 2004, p. 120).

The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).
Ecological Soil Screening Level for Iron Risk assessment
plants are able to reduce iron from the ferric to the ferrous state, and allow iron uptake into the plant (Grussak, 1996). Significant amounts of iron are released into the environment as a result of coal mining. During these operations, pyrite (FeS2), which is found in coal seams, is exposed to air and water and is

Coal, Kentucky Geological Survey, University of Kentucky
Pyrite (FeS 2) is the most common sulfide mineral in coal and a major source of the sulfur in coal.Pyrite can form in peat while the peat is accumulating, or can form in peats from the introduction of sulfate (SO 4) into the peat if the peat was buried by marine waters (such pyrite is called syngenetic or authigenic pyrite).Within the buried peat, the sulfate is reduced to sulfide (S 2), which
Pyrite is unstable and oxidizes easily, which is an issue in controlling acid mine drainage. Pyrite is a widespread natural source of arsenic, which can leach into groundwater aquifers when geologic strata containing pyrite are exposed to the air and water, during coal mining for example.
