ispersant thickened tailings

Sixtailingssamples have been tested in this research: a typical untreated FFT and fivethickened tailings(TT 1 to TT 5) that were all flocculated andthickened. Samples TT 3 and TT 4 were used to evaluate the effect of flocculent dosage, and samples TT 2 and TT 5 were subjected to freeze–thaw cycling to evaluate the effect of this treatment.

Thethickeningand filtering processes produce driertailings, which can be stacked and compacted by conveying and spreading equipment in multiple lifts per pad (IM, 2016). The dry stackedtailingsarea can be used to start the revegetation process much earlier and the stacks can be contoured to blend in with the local landscape.
