  • A Study on High-Grade Iron ore Beneficiation to

    2020-5-21 · Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is always preferred.

  • Reducing alumina, silica and phosphorous in iron ore

  • BENEFICIATION STUDIES ON IRON ORES OF BIHAR

    2011-8-3 · (a) The iron ore samples received were from Noamundi I, Noamundi II, Joda, Badampahar and Gorumahisani Mines. Those from Noamundi I, Noamundi II and Joda consisted mostly of hematite with a smaller proportion of hydrated iron oxides, goethite, lepidocrocite and limonite. Kaolin and laterite accounted for the bulk of alumina in these ores.
