HYDRAULIC TAILINGS

consolidation characteristics in their clay slimes (Bromwell and Raden 1979; Schiffman et al. 1988). A void ratio of 0.8 to 1.3 is typical of many slimes deposits, with (N1 ) values often ranging from 1 to 3. Of particular significance to slope engineering issues is the high specific retention of void water exhibited by slimes.
