Abstract Major impurity elements in iron ore are silicon, aluminum, phosphorus, and sulfur. Often, a chemical separation is the only method able to remove phosphorus from iron ores. Phosphorus can occur as phosphorus-containing minerals (e.g., apatite) and being finely dispersed in hematite in oolitic ironstones or in goethite in goethite–hematite banded iron …

C + O2 → CO2. The heat produced by this reaction is the main source of heat in the blast furnace that is used for iron production. At the bottom of the furnace, the temperature is very high, which causes more of the coke to react with carbon dioxide, producing carbon monoxide. C + CO2 → 2CO. The carbon monoxide then becomes the "reducing ...

The frothed ore collects on the oil section whereas the impurities settle down in the water medium. Chemical Separation: One way of concentrating the ore is by chemical separation. For example, the separation of aluminium (Al) from the bauxite ore. This process of separating aluminium from the bauxite ore is also termed Bayer's Process.
