[pdf] Review Of Organic Binders For Iron Ore Agglomeration
Introduction Iron ore pellets are one type of iron-rich, intermediate product used during primary iron and steel making. During pellet production, fine-grained iron containing minerals are liberated from lowgrade ores, concentrated, and agglomerated into round balls that are thermally hardened to form “pellets”. Pellets are then transported to Blast Furnace or Direct Reduction operations.

Application Of Biotechnology In Iron Ore Beneficiation
Jan 01, 2015 Bioleaching for phosphorus removal from iron ores. Dephosphorization of iron ore can be achieved through bioleaching. Different methods are needed to remove phosphorus from iron ore depending on whether it is present as a mineral (apatite) or associated with iron minerals (Edwards et al., 2011). Although most phosphorus occurs entrapped within.

(pdf) The Removal Of Phosphorus From Iron Ore By Leaching
Very little information has been published on iron ore dephosphorization by acid leaching [2]. during the period 1964-1973, some processes were operated in Sweden where the iron ore was leached with nitric acid. In those processes, the phosphorus content in the ore was reduced from 0.2 to less than 0.05 .

Reaction Behavior Of Phosphorus In Coal
Coal-based reduction followed by magnetic separation is an effective way to recover iron from high phosphorus-containing oolitic hematite ore. Given that high quantities of dephosphorization agent are needed to obtain low phosphorus reduced iron, a novel approach is proposed by the authors. Without prior phosphorus removal, the phosphorus was enriched in the reduced iron during a reduction.

Review Steelmaking Technology For The Last 100 Years
Unavoidable use of P-bearing iron ore (0.2–0.3 P) for blast furnace due to the war time shortage of low P ore imports. To improve dephosphorization (deP), refining the converter melt with BOH was attempted by the name of Converter-BOH Combination process (double refining). However, the process was found 6 lower in metal yield and 14 higher.
