Cover Story: Copper and zinc mine tailings can become the next generation of aggregates for most civil engineering applications. However, this high-density material cannot be used in its raw state due to the high levels of sulphur and other heavy metals (As, Cr, Cu, Pb, Zn). This study focuses on the stabilisation of high-sulphur tailings, without thermal treatment, using alkali-activated fly ash. There was an increase in strength due to the formation of a N-A-S-H gel, although sodium sulphate carbonate also developed, suggesting that the total sodium content can be optimised. The solubility of the metals was below the threshold for non-hazardous waste. View this paper.
