Tailings vary, from overburden, which is the waste rock, to other material that encases an ore or mineral body, and which is displaced without processing during mining,” explains Loots.

Iron ore tailings as a supplementary cementitious material

In this paper, the characterisation of iron ore tailings (IOT) was carried out to examine its use as a supplementary cementitious material (SCM) to produce coloured composite cements. The IOT was heat treated, and ten different mixtures were prepared, substituting Portland cement for 10, 20 and 30 wt%.
