The ore from location 722 contains 46.2% Fe and correlates to the low-grade ores although it has a relatively high content of gangue materials (about 49.3%). The total iron content of most exported iron ores in the world is in the range of 6264% [7]. Therefore, the average quality of ironSuccessful beneficiation has been achieved on both the crude Snake River ore and a jig concentrate, with some concentrates assaying 69.0% Fe and <0.03% P (iron-ore specification is 0.07% P max.).(PDF) Characterization of Selected Mineral Ores in the

Phytoremediation: A Novel Approach for Utilization of Iron-ore
In India, iron-ore beneficiation proceeds mainly from washing, sizing by classification, jigging and then magnetic separation. The advantage of washing is to impart better handling properties to the ores, particularly the removal of fines, which becomes sticky in the rainy season and may pose problems during transportation to steel plants.Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied(PDF) An overview of the beneficiation of iron ores via

Mineral and Technological Features of Magnetite–Hematite
Analysis of the current technical solutions for the processing of iron ores showed that the high-grade ores are directly exposed to metallurgical processing; by comparison, low-grade ores, depending on the mineralogical and material composition, are directed to beneficiation including gravitational, magnetic, and flotation processes or their Non-magnetic physical separation of hematitic/goethitic iron ore.

Beneficiation of Clay-Rich High-LOI Low-Grade Iron Ore
The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite 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 Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore.
