Hydraulic Conductivity and Soil Water Retention of Waste Rock and Tailings Mixtures
The objectives of this study were to (i) measure the hydraulic conductivity and soil water retention of tailings and waste rock and tailings mixtures and (ii) assess how the tailings fraction influences hydraulic properties of the mixtures. Mine tailings and waste rock were collected from two mines, and tailings-dominated mixtures (i.e., GeoWaste) were created whereby waste rock particles act as inclusions in the tailings matrix. Hydraulic conductivity of pure tailings ranged between 9×10-6 and 7×10-8 cm/s, whereas hydraulic conductivity of GeoWaste ranged between 1×10-4 and 3×10-8 cm/s. The hydraulic conductivity of GeoWaste decreased with an increase in effective stress from 10 to 100 kPa, and was comparable to hydraulic conductivity of pure tailings at effective stresses of 100 and 500 kPa. Similarity in the water retention behavior of GeoWaste and pure tailings was dependent on the mixture ratio, whereby mixtures with larger tailings fractions exhibited more comparable soil water retention to pure tailings.
