The medium grade iron ores contain high ultrafine fractions of soft slime which result in poor dewatering characteristics. Herein, a detailed study was conducted to assess the settling behaviour of iron slimes or tailings using a novel starch-based binary graft copolymeric flocculant (St-g-(pAAm-co-pSS)) and the performance was compared with four commercial reagents.

This report describes the results obtained from field tests and small-scale continuous dewatering tests on coal-clay waste, bentonitic waste, and phosphate clay waste. Dewatering of Ultrafine Bentonitic Waste. Bentonites are used in drilling muds, foundry sands, and pelletizing of taconite iron ores (S. G. Amplan, 1975).

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 challenges.

In this paper the bench and full-scale flocculation behavior of iron ore tailings is investigated in order to improve the dewatering performance of tailings thickeners of an iron beneficiation plant. In the batch settling tests, the effect of flocculant dosage (5–20 g/t solid), …

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 ...

New heavy mineral spiral for recovery of ultrafine chromite. Spiral concentrators are gravity separation units which are cost and energy efficient. They are widely used to treat various minerals such as coal, iron ore and chromite ore. Separation is based on the difference in the specific gravity of the compounds in the mineral ore.

The desliming prepares the ore for flotation, discarding the ultrafine particles. The underflow from the desliming thickener is sent to a series of finisher magnetic separators to further purify the solution. The overflow from this thickener reports to the tailings thickener. Reverse Flotation Cells

Beneficiation of coal is a water intensive process, and the water is recovered in downstream operations in the high rate thickener (HRT) and vacuum belt filtration (VBF). Clean coal particles entering the HRT have an inherent tendency to enter the overflow because they are extremely fine and hydrophobic. Hence, flocculants (polymers) are used to floc the ultrafine particles so that …

"Decreasing ore grades mean that mines are producing more tailings than ever before. One of the challenges with tailings management is that there cannot be a one-size-fits-all approach; each mine requires a tailored solution that carefully considers the minerals being processed, as well as the site's climatic and geological conditions.
