2016-8-18  Separation of iron and rare earths is theoretically possible by carbothermic reduction and could be used as an alternative to physical upgrading of the ore. As shown in the Ellingham diagram for pure oxides in Figure 1, iron oxide can be selectively reduced over rare-earth oxides; however, in the present case, smelting would be required to enable efficient separation of iron metal from REO-bearing slag. REO are stable under the iron smelting conditions generally described by the temperature and oxygen partial pressure, therefore they will report to the slag phase whilst the iron will report to the metal phase. Although this separation

Iron ore mining and dressing - tec-science

2018-6-21  Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.
