    • Phosphorus Impurities Iron Ore - vollendam

      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
