Iron ore filtration process improvement through pH modification
The present study presents the effect of pH reduction in iron ore slurry for an iron ore filtration process. A reduction on moisture content and increase on filters throughput was proposed by the pH modification. The experimental procedure included bench scale tests and industrial scale up of the observed results. Additionally, Langelier’s

Iron Ore Statistics and Information U.S. Geological Survey - USGS.gov
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries. The seven largest of these producing countries ...

Understanding Iron Ores and Mining of Iron Ore – IspatGuru
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.
