- Dewatering Waste Of Iron Ore
Dewatered tailings technology filters and extracts water from ore processing waste to produce a paste or bulk cake-like consistency. How much water can be removed depends on the type of tailings, but in a classic dewatered set-up, experts say volumes are expected to be reduced by around 30–40%.

If too much water mixes with iron ore, it becomes low grade and unsuitable for export, which results in massive revenue losses. Also, surface dewatering processes are extremely costly if the water is very high. The accepted dewatering process within the region is to pump the water out through boreholes. However, this is not without its …

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 ...

Large mine sites or those with complex ore bodies can produce many different tailings waste slurries which may require varying methods of treatment. Across this multitude of situations, the operator must determine all associated costs and assess the level of dewatering required to confirm the most suitable solution for their site.

Therefore, dewatering after 1250 kPa filtration has no further adhesion-increasing effect. For the iron ore tailings, 5 kN·m −2 corresponds approximately to 25 mm cake thickness by assuming a residual moisture of 20 w-%, ρ Solid of 3050 kg·m −3, ρ Fluid of 1000 kg·m −3, a full saturated cake (S = 1) and no sealing edge.
