Iron ore is an important raw material for steel production. According to statistics world iron ore production increased from Bt in 2001 to Bt in 2012 .Due to the increasing consumption of highgrade iron ore the iron content in iron ore is decreasing and these iron ores have to be finely ground and beneficiated to enrich the formation of iron concentrates which are then
Jun 4 2022The unutilized iron ore fines (IOF − 10 mm 45 to < 60 Fe(T)) left at various mine sites during blasting and processing are rich in goethetichematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay containing below 45 μm is mostly brittle
This laboratory study investigates selective grinding and beneficiation options for a Greek bauxite ore.
