Phosphate Minerals an overview ScienceDirect Topics

Large numbers of phosphate minerals occur in the oxidized zones of base metal ore bodies. Solubility phenomena play the most important role in determining which phosphates crystallize in these low-temperature environments, where generally acidic groundwaters dominate. Phosphates of Pb 2 + are generally the least soluble, so these minerals, particularly pyromorphite (Fig. 12), are prominent in

Phosphate Mineral an overview ScienceDirect Topics

In high-phosphorus iron ore deposits, the phosphorus is present either as discrete phosphate minerals (e.g., apatite) or as a phosphate in iron oxide and oxyhydroxide minerals in the ore. High impurity levels of silicon, aluminum, and sulfur in the ores are usually due to the presence of mineral impurities (e.g., quartz, kaolinite, pyrite, and gypsum).

Goethite

Composition. Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is more typically massive.. Feroxyhyte and lepidocrocite are both polymorphs of the iron
