PDF-What is Pyrite Oxidation?

Pyrite FeS is one of the most widespread and persistent minerals and occurs in sedimentary metamorphic and igneous rocks Pyrite grows in crystalline forms typically cubic octahedral or more r.

Salt on icy roads can make driving safer, but the salt that clings to the metallic parts of cars can cause them to corrode or rust relatively quickly. This corrosion is one example of a chemical reaction called oxidation-reduction. You will learn about oxidation-reduction reactions..

Fool’s Gold vs. Gold. Talk to the students about prospecting for gold and how many miners were fooled by something that looks a lot like gold called pyrite. The students will work in small groups to compare samples of fool’s gold and real gold. They will use the attached worksheet to document their findings and make a prediction on which sample is the real gold. The class will reconvene to hear which indicators mean gold and which mean fool’s gold to check their prediction. . Oxidation and reduction. Oxidation and reduction – oxygen . transer.
