Understanding Iron Ores and Mining of Iron Ore – IspatGuru

03/04/2015  Mining (extraction), beneficiation, and processing of iron ore produces iron and steel. Mining is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. High grade iron ores (iron content greater than 62 %) are simply crushed, screened and shipped directly to the iron making unit (e.g. blast furnace). Low grade iron ores containing lower iron ...

Iron. During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities). Air which is heated to about 1200°C is blown into the furnace through nozzles in the lower section. The air causes the coke to burn, producing carbon monoxide which reacts with the iron ore, as well
