  Dry beneficiation of low-grade goethite-rich iron ore fines …

  In mining and minerals industries, whenever water supplies are restricted and also where wet processing leads to problems in handling and dewatering of the products and tailings, dry beneficiation is preferred. Moreover, the decrease in available high-grade iron ores has generated a need to develop alternative beneficiation processes for processing low-grade …

  A Beneficiation Study on a Low Grade Iron Ore by Gravity …

  2018825 · In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The …
