What is Pyrite? Pyrite is a brass-yellow mineral with a bright metallic luster.It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral.It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many …

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/MBS takes effect at around pH 6.

An additional reason for removing pyrite prior to burning is conservation of the mineral value. In 1969, over 300 million short tons of coal was burned by electric utilities in the United States. If it is assumed that these coals averaged 2 pct pyrite, 6 million tons of pyrite (53 pct sulfur-47 pct iron) was converted to SO2 and iron compounds.

This is because the froth is becoming purer as the unwanted mineral, the iron pyrite, is being cleaned off of the bubble. Not only is the colour of the bubble changing but the size is as well, the weight that the bubble has to support is lessening as the impurities and un-liberated (locked) valuables are depressed.

image: 2 different formats of pyrite crystals. One of the key factors in the formation of cubed pyrite crystals is the presence of sulfur and iron ions in the solution. These ions are necessary for the formation of the mineral, and the ratio of sulfur to iron in the solution can play a role in the size and shape of the resulting crystals.

Historically, pyrite was used commercially as a source of sulfur, particularly for the production of sulfuric acid, but today sulfur is largely collected as a by-product of petroleum processing.Because of the availability of much better sources of iron, pyrite is not generally used as an iron ore..

Iron ore does not exist pure in nature. Its most common compounds are hematite (limestone), limonite, magnetic iron oxide, siderite and pyrite. Pure iron is obtained by reduction of iron oxide in a hydrogen stream or by electrolysis of iron sulfate solution. Pure iron can be processed and purified easily, but iron must go through certain stages.

The three most important iron minerals in cyanidation are pyrite, marcasite and pyrrhotite. These minerals decompose in cyanide solutions in the order given, i.e., pyrite is the most stable and pyrrhotite the least. Pyrite, FeS2, is insoluble in hydrochloric acid, but decomposes readily in nitric acid, most of the sulphur going to sulphuric acid.

At Bannockburn, in the Madoc area, a pyrite deposit was discovered below the limonite, which was being mined as an iron ore; this gossan capping of the pyrite was from eight to fifteen feet deep. In the old iron mines near Londonderry, Nova Scotia, the ore was limonite in fissures originally filled with siderite and other carbonates.
