Pyrite Mineral Uses and Properties

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 ROASTING AN ALTERNATIVE TO SULPHUR BURNING M Runkel

minerals including solid fuels and for metallurgical processes both in the ferrous and non-ferrous fields. Process appli ions have included roasting calcining combustion and charring of coals as well as off-gas treatment. This paper provides a summary of the pyrite roasting technology currently used along

How do you solve this chem problem? Yahoo Answers

In a metallurgical process the mineral pyrite FeS2 is roasted in air: FeS2 O2 >> Fe2O3 SO2 The SO2 is then converted into H2SO4 in the following reactions: 2SO2 O2 >> 2SO3 SO3 H2SO4 >> H2S2O7 H2S2O7 H2O >> 2H2SO4 Assuming the mineral is 24.0% FeS2 and the remainder is inert what mass of H2SO4 is produced if 155g of the mineral is used?

Transformations of pyrite during formation of metallurgical

The desulfurization of pyrite during the coking process leads to the formation of phases of varying size shape and composition. The phases are represented mostly by Fe and S-bearing associations which can be divided into two egories: those represented only by of Fe–S phases three varieties and aggregates containing both sulfides and almost pure iron.

Transformations of pyrite during formation of metallurgical coke

Depending on the initial mineral in the coal sulfur-bearing minerals will be transformed at the end of coking process into the following phases: pyrrhotite wurtzite Cu–Fe–S melt CaS and BaS.

PYRITE: THE STRATEGIC MINERAL THAT BECAME AN INDUSTRIAL NUISANCE

when other sources of cheap elemental sulfur became available pyrite not only lost its importance but became a nuisance for the metallurgical industry because of problems associated with its disposal. At present only pyrite-containing gold is treated by a variety of methods to recover gold. KEY WORDS: Pyrite metallurgical industry. Figure 1.

Solved: In A Metallurgical Process The Mineral Pyrite FeS

In a metallurgical process the mineral pyrite FeS2 is roasted in air: The SO2 is then converted into H2S04 via the following reaction: Assuming the mineral is 24.0% FeS2 and the remainder is inert what mass of H2SO4 is FeS2 O2 Fe2O3 SOz unbalanced 2SO2 O2 H2O SOg H2SO4 produced if 155 g of the mineral is used?
