Iron ore tailings generated during beneficiation process of low grade iron ore fines from Rungta mines, Barbil, Odisha, India were used for the present studies. The slurry density of tailings received for dewatering studies was 1125–1200 kg m −3 and the particle density was around 3500–3600 kg m −3. The Magnafloc-1011 an anionic and ...

choice for high-capacity concentrate dewatering with the lowest operating costs. In one case, this meant increasing throughput to more than 500 t/h per machine, with half the total footprint of traditional solutions. In a different brownfield project, the result was the world's largest hyperbaric disc filter in iron ore production, with a

Improved dewatering of iron ore fines by the use of surfactants, The bed of the iron ore fines formed on the dewatering screen can be thought of as a cake of fine and ultrafine mineral particles on a filter cloth, Hakkinen A, Ekberg B, Dewatering of Iron Ore Slurry by,

McLanahan's director of process engineering for mineral processing, Scott O'Brien, explained the rationale for using this approach to dewatering. O'Brien said while using a thickener on its own will enable an operator to recover 80%-90% of the water in a slurry, the underflow will still contain enough water to make it difficult to handle ...

The size classification of iron ore tailings is shown in Fig. 1 (a).It can be seen from the figure that d 80, d 50, and d 20 of the tailings are 12, 5 and 2 μm, respectively. The wet chemical analysis of iron ore tailings indicates that it mostly contains 40% Fe, 18% SiO 2, 14% Al 2 O 3, 0.56% CaO, 0.27% MgO and 7% LOI (Loss of Ignition).The mineral …

The influence of certain surfactants on the dewatering of fine iron ore sludge flocculated with anionic flocculants has been investigated in a laboratory-scale vacuum filtration unit.

Many iron ore mines reached the water table in the 80's, developing hydrogeological studies to promote the mine's dewatering. These studies improved a lot the understanding of the groundwater behaviour of the Quadrilátero Ferrífero. This is the case of Minerações Brasileiras Reunidas S/A – MBR, an iron ore mining company that, during ...

The present invention is related to a high aspect ratio column thickener and a process thereof useful for dewatering of iron ore tailings. The column thickener has been developed with multiple feed inlet points and an auxiliary inlet point for water to clear the jam of high concentration slurry, if required. The column also consists of a conical portion at the bottom.

The bed of the iron ore fines formed on the dewatering screen can be thought of as a cake of fine and ultrafine mineral particles on a filter cloth. The dewatering phenomenon is often quantified by the Laplace–Young equation, which relates the pressure necessary to drain a capillary to the surface tension, contact angle and a nominal ...

Thus, considerable quantities of ultrafine particles of iron oxides, silicates, and aluminumsilicates find their way to tailing suspension, whose total iron content can vary from 40% to 50% [5 ...
