Magnetite and Chromitite ores (both iron ores) use this method on a large scale to remove their impurities. Learn the process of extracting Crude Metal from Concentrated Ore. Froth Flotation Process. Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores.
The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore : Concentration of ore: In this metallurgical operation, the ore is concentrated by removing impurities like soil etc. The process involves the crushing and washing of ore.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
