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.

WhatsAppGet PriceGet A QuoteNow, first of all, pure iron is rarely available (except if one or two meteorites crash). 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.
WhatsAppGet PriceGet A QuoteThis means that the mined iron ores need to be specially processed in advance before the blast furnace process. Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China
