Understanding Iron Ores and Mining of Iron Ore – IspatGuru

03/04/2015  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 content need beneficiation activities other than crushing, screening and washing for increasing their iron content.
