In addition, the hydraulic conductivities of the two tested fine tailings are smaller than those of the copper and gold tailings from Qiu and Sego , and larger than that of the fine oil sand tailings from Wong et al. . Compared to the organic tailings, the metal tailings generally present a larger hydraulic

In this state, the filtered tailings are often termed dry stacked tail-ings, since the materials resemble a moist sand that can be stacked and compacted into a stable landform. In the design of dry stack tailings facilities, it is important to consider the materials charac-

Oct 12, 2016 Hydraulic conductivity was measured on pure tailings and fly ash-amended tailings in flexible-wall permeameters. Fly ash was added to mine tailings to constitute 10 dry mass of the mixture, and specimens were cured for 7 and 28 days. The influence of fly ash-amendment on k of mine tailings was attributed to 1 molding water content and 2 ...
