Efficient pyrite activating persulfate process for ...

Jan 15, 2017  This study suggests that the persulfate-pyrite system is an effective oxidant process for PCA degradation. In the persulfate-pyrite system, Fe 2+ released from the pyrite facilitated persulfate decomposition to form sulfate radicals. Increased pyrite dosages and dissolved oxygen concentration resulted in enhanced PCA degradation.

Pyrite (FeS 2) is an abundant sulfide-associated iron mineral that exists in the earth.In this study, the pyrite/oxone process was demonstrated to be an effective approach for the catalytic degradation of propanil, where more than 90% decay ([propanil] 0 = 0.01 mM) was achieved within 15 min. Typically, the effects of various experimental parameters, including catalyst loading, oxone dosage ...

Pyrite Mineral Uses and Properties

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 geologists would consider it to be a ubiquitous mineral.

Highly Efficient Rhodamine B Decolorization by Pyrite ...

Apr 05, 2021  In this study, pyrite/peroxymonosulfate (PMS)/hydroxylamine (HA) system could decolorize rhodamine B (RhB) in a wide pH range of 3.0-10.0. Near-100% decolorization of RhB was realized under optimum conditions of pyrite 0.4 g L−1, HA 0.8 mM, PMS 1.6 mM, and initial pH 4.0. Radical (mainly SO4•−) oxidation was the dominant process for RhB decolorization by pyrite

Pyrite Tailings Recovery by Flotation

Mar 19, 2017  Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a ...

PYRITE ROASTING, AN ALTERNATIVE TO SULPHUR BURNING

Pyrite roasting and sulphur burning plants are built for the production of sulphuric acid. 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
