Experimental Simulation of Long Term Weathering in Alkaline Bauxite Residue Tailings

Metals, 2015
Bauxite residue is an alkaline, saline tailings material generated as a byproduct of the Bayer process used for alumina refining. Developing effective plans for the long term management of potential environmental impacts associated with storage of these ...
