· Acid mine drainage (AMD) occurs when metal sulfides, most commonly pyrite, are exposed to and react with air and water. When water flows over or through sulfur-bearing mine tailings, a chemical reaction occurs between the water and rocks resulting in metal-rich water. AMD typically has a bright orange, yellow, or bownish-red color to it.
Commonly called fool''s gold, pyrite is the Earth''s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore. Pyrite Uses
· Flotation process of Copper-Pyrite minerals. The flotation section is composed of two 8-cell "Sub-A" Flotation Machines. The copper section has four rougher cells, two scavenger cells and two cleaner cells for dual cleaning of the rougher concentrates. The rougher copper froth passes to the cleaner cells and the scavenger froth to the ...
wastes a principal weathering process is the sulphide oxidation, resulting in low pH and mobilizing heavy metal contamination. Usually the extracted sulphidic ores consist of different metal sulphides with various oxidation rates. The most common, iron-bearing sulphides – pyrite, pyrrhotite – usually

· According to the inhibiting principle of pyrite, iron pyrite can generate a strong hydrophilic thin film with hydroxyl ion on pyrite surface under the alkaline environment. After the inhibition operation, pyrite must be activated in the process of lead-zinc tailings recovery.
· Pyrite oxidation, which can lead to acid mine drainage, is a concern for miners all across the globe. However, little is known about the processes that cause this phenomenon.
The beneficiation process increased the pyrite content of the R1 fraction and generated two solid waste products with distinct characteristics: one with a high calorific value of 2339.00 kcal/kg and another one rich in iron oxide sulfate hydroxide (Fe 3.6 Fe 0.9 (O,OH,SO 4) 9). After remediation by simple distillation, the effluents from the ...
process relevant figures are the sulphur content and the particle grain size. Additional important process figures are the reaction temperature and the concentrate throughput. The pyrite concentrates can be classified as: Type Composition Grain Size Pyrite Concentrate (flotation) S 47-48 wt%; Fe 42–43 wt% fine particles 55% < 45µm
Iron ore is an important raw material for iron and steel production enterprises. After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals (iron ore). It is the mineral aggregates that contain iron or iron compounds which can be used economically. Production Process of Iron Ore

· This process is suitable for mines with small production scale and high grade. For example, a gold concentrator processes typical iron-gold ore, with a processing capacity of 200 tons/day and a gold grade of 10 grams/ton. All ores are calcined in a rotary calciner. The calcined ore is transported into the percolation tank with a mining cart.
During strip-mining, overburden materials consisting of iron disulphide (FeS 2, pyrite) minerals upon exposure to air and moisture oxidize and produce acid and soluble salts. Iron disulphide is a chemically reduced substance; when exposed to oxygen and water results in the oxidation of FeS 2 to H 2 SO 4 by a complex series of chemical reactions: 1.
Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron sulphide crystals begin to grow.

How Iron Pyrite is Formed. Iron pyrites is a metallic mineral made of iron and sulphur (FeS2). It is often found in mineral veins, and as pyrite nodules. It is a heavy stone with a yellowish sheen, or if exposed to oxygen pyrite may also take on a rusty red hue where it has started to oxidise. In its crystalline form it has shiny brass-coloured ...
ENVIRONMENTAL IMPACTS OF METAL ORE MINING AND IRON MOUNTAIN 3 1. Introduction Iron Mountain is a historical mining operation that operated from the 1860''s to 1963. The mountain itself is described as a massive iron sulfide deposit where iron, copper, gold, pyrite…
This process is accelerated by the action of Acidithiobacillus bacteria which oxidize pyrite to produce ferrous iron, sulfate, and protons (H + These reactions occur more rapidly when pyrite is finely dispersed (framboidal crystals initially formed by sulfate reducing bacteria (SRB) in argillaceous sediments or dust from mining operations).
Iron pyrite is a naturally pure and hugely useful ore of iron, finding applications in areas as diverse as photovoltaic cells, brake pads and as a glass colourant. African Pegmatite is a leading supplier of iron pyrite, with the ability to provide the material in a range of grind sizes suited to any operational need.

· It is commonly believed that the iron ions in leachate come from pyrite or its roasted product. However, the process of pyrite combustion is complicated, and depends on combustion parameters such as temperature, particle size, ﬂow condition and the atmosphere [13–15].

The mineral pyrite (FeS 2) and other sulfur containing minerals are common. Also common is the occurrence of these minerals in the geologic strata in the vicinity of coal seams. Mining coal inevitably involves exposing these pyritic materials to oxygen and water. In deep mines, these materials are exposed in the voids created by the mining process.
The proposed treatment for effluents generated during the coal mining pyrite beneficiation process, which includes the partial distillation of these effluents and subsequent addition of 95% ethyl alcohol, was adequate to obtain calcium and iron compounds separately in the form of sulfates .

Further exploration near the deposit and further development drilling within the deposit are done while the mining is ongoing. Comminution (i.e., the breaking of rock to facilitate the separation of ore minerals from waste) combines blasting (a unit process of mining) with crushing and grinding (processing steps).
