Goethite formule
WebJarosite is a basic hydrous sulfate of potassium and ferric iron (Fe-III) with a chemical formula of KFe 3 (SO 4) 2 (OH) 6. This sulfate mineral is formed in ore deposits by the oxidation of iron sulfides. WebGoethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. …
