Effect of <i>Oligochaete</i> worms on the permeability of fluid fine tailings and thickened tailings under operational parameters: consequences for dewatering and strengthening
Oligochaete worms enhance dewatering of mature fine tailings. In this context, the research team has investigated the beneficial effects of Oligochaete worms in dewatering and strengthening of fresh samples of fluid fine tailings (FFTs) and thickened tailings (TTs), including cold temperatures. Applying Oligochaete worms to FFT and TT resulted in enhanced permeability leading to faster solid content ( S c ) increases that are twice as large as in controls, up to final S c of 37% for FFT and 61% for TT, and shear strengths that are twice as large in their absolute value as in controls too.
