Utilization of Copper Mine Tailings as Road Construction ...

Abstract. This research studies the feasibility of using copper mine tailings (MT) as an alternative road construction material through geopolymerization. First, an extensive literature review on the use of MT as road construction material was performed. The utilization of MT in road construction can be divided into two general categories based ...

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
