Developments In Chemical Separation Of Iron Ore

Developments In Chemical Separation Of Iron Ore

Jan 01, 2015 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.
