Iron Ore Mining | Techniques | Metal Extraction

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines Manual mining method is normally limited to float ores and small mines Mining of reef ore is also being done manually on a small scale The float ore area is dug up23/10/2017· It has to be derived from iron ore that occurs near the surface when mining Then the iron derived after a long processing in the blast furnace is handed over to the iron and steel industry to make a huge amount of useful materials Most of the iron, however, is used in the construction industry In fact, the entire construction sector is highly dependent on the Iron &The StepbyStep Process of Producing Iron from Iron Ore
