WhatsApp: +86 18838072829The leadzinc mill tailings used in this present study can be classified under the category of coarser tailings as the fines fraction (<20 μm) in the tailings is about 22% [45]. The D 50 ( μm) of fly ash is lesser than the mill tailings (D 50 = μm). Hence, it is evident that the fly ash samples are relatively finer than the tailings.
