Experimental Evaluation of PM Emission from Red Mud Basins Exposed to Wind Erosion

The disposal of industrial and mineral processing residues represents a major concern for human health the environment as whole. In order to reduce impact on soil groundwater due waste leachability, implementation environmental regulations worldwide has favored conversion techniques from wet dry (i.e., stacking or disposal). Such change in storage practice may cause increase particulate matter (PM) emission surfaces tailings exposed wind erosion. Considering significance issue global scale increasingly stricter orientation policies, need modeling tools capable estimating contribution tailing basins air pollution becomes apparent. paper deals with red mud resulting bauxite alumina industry.
