Screening 101. Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower ...

The washing of the iron ore fines results in a moisture of about 11–14% in the fines and about 4% in the sized ore. The moisture content goes up to 16–18% in the fines during the monsoon season. Indian iron ore contains hematite and goethite as the major iron bearing minerals. Alumino-silicates are the gangue minerals [10], [11], [14], [15 ...

Results indicated that LD iron ore exhibited free flow at dry condition and very poor flow at 8%, 10% and 12% moistures. In the presence of SAP, LD iron ore has changed its flow behaviour to easy flow regime due to their high affinity for moisture absorption. Optimum dosages of SAP were found to be 1200 ppm, 1400 ppm and 1800 ppm for …

Current industrial practice of processing of iron ore fines in India does not involve much beneficiation. However, few plants in India are treating fines during washing, classification, and jigging process [4].
