the beneficiation of iron ore slimes produced from washing plants and tailing ponds of kiruburu mines was studied using wet high-intensity magnetic separators (whims) followed by classification in hydro-cyclone whereby a concentrate assaying 63 % fe and 3.3 % alumina was produced with an overall iron recovery of 56 %. though multi-gravity .
the upper limit of the ore particle size is related to the ore size, embedding characteristics and equipment size. in usually, the ore is 50-150mm, and the coal is 300-500mm. dms can greatly reduce the surrounding rock and waste rock under the same processing capacity, reduce ore grinding consumption, thus reduce production costs.
it is typically operated at a pulp density of 25 to 30% and mostly processed after the classification of the super fines using a hydrocyclone. the kirondal iron ore plant of essar steel limited has successfully applied the spiral technique for the beneficiation of iron ore slimes to achieve a pellet feed concentrate.
the iron ore industries of india are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. with the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. however, most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable .
For model validation, pilot-scale hydrocyclone beneficiation experiments were performed on an iron ore blend, using different hydrocyclone pressures and percent solids in the feed pulp. model parameters were determined from one set of experimental results and the calibrated model was then used to predict the outcomes of the two subsequent .
