Recovery of Ultra-Fine Iron Ore from Iron Ore Tailings

2017-9-14  Here the study focuses on the application of selective flocculation process for beneficiation of synthetic mixtures of iron ore and kaolinite as well as iron ore tailings. Results show that it is possible to achieve 65.78(%) of Fe, with 2.65% Al 2 O 3,3.66 SiO 2 (%) in the concentrate using synthetic mixture feed and more than 60% of Fe is obtained from natural iron ore tailings.

Re-beneficiation of iron ore tailings GoodRich

Once the iron ore becomes magnetite, it is much easier to beneficiate pelletise it. The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants).

Innovative Technique to generate saleable Iron Ore Fines

Earlier Iron ore tailings contain iron concentrations of around 45% or more. In future it may become economically viable to extract the iron content from tailings, and due to the high cost of land and environmental factors it is worthwhile attempting to minimize tailings volumes. Further RD study was conducted for more recovery of saleable fines from on line tailings by wet high intensity magnetic separator, which resulted in to positive impact. A pilot-scale test was done on the continuous type model plant, and the different operations involved are described further. Sesa-codli iron ore tailings were subjected to a laboratory-scale test. By desliming cyclones it was possible to produce concentrate with Fe content of 54%. Desliming cyclones concentrate were subjected for WHIMS tests. It was found that there was appreciable recovery of Fe (up to 60%), and Al2O3 and SiO2 content could be reduced by 50%. The installation of WHIMS plant has enabled resource recovery, reducing the quantity of tailings by about 13%. A scheme for the WHIMS plant for the utilization of tailings for resource recovery

Recovery of values from tailing ponds of iron ore

Most of the Iron ore washing plants set up in India in the earlier days consist of sizing of the ore by dry / wet screening, washing and classification by screw classifiers. In this classical approach, iron values were lost in the form of fines and utrafines into the tailing ponds as they had little commercial value in those days and accumulated in huge quantities over the years.
