Iron Ore Recovery from Low Grade by using Advance Methods

Jan 01, 2015· The main difficulty inprocessingand utilization of low-gradeironores primarily stems from their mineralogical characteristics as well as the soft nature of some ores and their high silica content. Thus, beneficiating the low-gradeironores to remove the gangue minerals and enhancing their grade is an attractive proposition today.

DryIron Ore Beneficiation Iron OreSeparation ST

Iron oreextraction is mainly performed through open pit mining operations, resulting in significant tailings generation. Theiron oreproduction system usually involves three stages: mining,processingand pelletizing activities. Of these,processingensures that an adequateirongrade and chemistry is achieved prior to the pelletizing stage.
