Pyrite - Wikipedia

Iron pyrite is unstable at Earth's surface: iron pyrite exposed to air and water decomposes into iron oxides and sulfate. This process is hastened by the action of Acidithiobacillus bacteria which oxidize the pyrite to produce ferrous iron and sulfate. These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the

Pyrite Mineral Uses and Properties

Other usesCharacteristicsPropertiesAppearanceCompositionIndustryUsesEffectsSafetyFormationThe name \"pyrite\" is after the Greek \"pyr\" meaning \"fire.\" This name was given because pyrite can be used to create the sparks needed for starting a fire if it is struck against metal or another hard material. Pieces of pyrite have also been used as a spark-producing material in flintlock firearms.

How to Separate Gold from Pyrite

When the ore was dehydrated by roasting in reverberatory furnaces the extremely fine particles of gold were agglomerated, and between 80 and 90 per cent, could then be extracted by amalgamation, the remainder being presumably coated by oxides of iron. The richness of the ore, however, made even this result unsatisfactory, and a process of

Different Types of Iron Ore - Mineral Processing Metallurgy

Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.

Pyrite Earth Sciences Museum University of Waterloo

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.
