Reprocess tailings. Really? Yes, really. If the technology exists today to remove up to 90% of water from mine tailings and, if a mining company is going to make that investment anyway to secure its future operations, then frankly, it is irresponsible not to consider reprocessing the tailings that currently sit in its TSFs.

The current contribution reviews past studies on the utilisation of mine tailings in cementitious (and "cement-like") matrices. This includes studies that used mine tailings as SCMs, as a raw material for clinker, as direct cement replacement (with or without activation) and alkali activated binders.
