coarse particle flotation, washed to remove salts, and then
used in concrete production, depending on the economics
of transportation. Clay or silt containing aluminosilicates
usually present in mineral slurries could be removed by fine
particle separation or as cyclone overflow, then dewatered
and dried. The process options are numerous and loca-
tion-specific, hence will not be discussed here. If suitable
aluminosilicate fines are not present in the tailings, mine
waste may be a suitable source. A CaO source such as lime-
stone or dolomite may be present at or near a mine site.
