The uses and properties of the mineral Pyrite. larger accumulations, the iron is easier to extract and the metal is not contaminated with sulfur, It depends upon how efficiently the gold can be recovered and the cost of the recovery process.
Reduction of iron ores using blast furnace cannot remove sulphur. So oxidation of iron pyrites is the manufacturing route which is not commercial today.
The mineral pyrite, or iron pyrite, also known as fools gold, is an iron sulfide with the chemical In the 15th century, new methods of such leaching began to replace the burning of sulfur as a . These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the form it takes in most mining operations.
