Copper Tailing an overview ScienceDirect Topics

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 0.06–0.002 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
