Hydraulic and physical characteristics of taconite tailings materials from several tailings basins in Northeast Minnesota were evaluated using laboratory and field techniques. A particle density of 3,085 g/cm**3 was determined as representative of all materials evaluated. Infiltration capacities ranges from 1. 09 cm/h on fine basin material to more than 12. 7 cm/h on unvegetated coarse dike material. Both hydraulic and physical properties exhibited much less variability than natural soils. Vegetated coarse dike surfaces had significantly higher infiltration capacities than similar unvegetated surfaces. However, there was no significant difference in infiltration capacities between vegetated and unvegetated medium and fine materials within the tailing basins.
