As copper tailings appear in ground form, the grading of copper tailings reported by Gupta and Thomas 2013 and Nitish et al. 2013 has a sizeable silt fraction of 0.060.002 mm. Copper tailings are considered to be finer than CS, which usually has a dominant sand fraction. Table 6.5 compares the geotechnical properties of copper tailings to those of CS, which have been reported in this
The use of the tailings in the construction of the dams is the most widespread method, due to the lower cost, material availability and constructive ease. In this case, the dams behave as dry stacks, which are structures constructed by the transport and deposition of soil in aqueous medium.
