Processing High-Grade Concentrates from Challenging Low ...

03.07.2013  On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired. This paper addresses some of these with examples on how technological

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. To be competitive, iron ore mining need to be done on a very

Iron ore pelletizing - Outotec

This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don’t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually
