PDF Pyrite Flotation A Review ResearchGateHow Is Pyrite Formed Reference

Pyrite Flotation A Review Sulfide minerals are semiconductors and pyrite is the major gangue mineral associated with these or Main interest in the processing of complex sulfide ores has Pyrite forms due to a chemical process initially caused by the decomposition of organic matter in bacterial sulfate reduction The bacterial sulfate reduction produces an inorganic anion known as bisulfide which reacts with iron minerals to form iron sulfides the most common of which is pyrite

Pyrite is a common accessory mineral in sedimentary rocks particularly in limestone sandstone and carbonaceous siltstones or shal Some times we wonder who and why it got there and what does it mean for petroleum explorationThe mineral is physically separated from the remaining pulp material and is removed for further processing The response of many minerals to the flotation process is often dramatically affected by pH Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite

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 The mineral pyrite / 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 form it takes in most mining operations

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 processPyrite roasting and sulphur burning plants are built for the production of sulphuric ac Whereas the burning of elemental sulphur is the main source for sulphuric acid the roasting process is an interesting alternative once pyrite concentrate is available In addition to these two applications Figure 1 shows a wider variety of sources for the
