The European Union legislation has been encouraging this type of practice, which is receiving full recognition from the international scientific literature as well. The application of the mining waste treatment as a reclamation technique is mostly based on the flotation technique that proved to be useful for separating the remaining minerals from the gangue. This provides both an environmental benefit and an economic advantage, which in some cases repays the re-processing costs, even though several difficulties could be encountered in the application of flotation to mining waste. The paper presents the results of the experimental laboratory batch tests, which proved to be encouraging in the case of the Montevecchio mining district (SW Sardinia). Nevertheless, future work is needed to clarify that they are valid for the different situations present on the site.

The aim of the EWT is the simulation of a part-depth Atmospheric Boundary Layer (ABL) and thus the reproduction of the wind flow over any type of surface. Experimental tests are currently being performed to analyse the correlation between the emission of dust from a variety of erodible samples and the influencing physical parameters (moisture content, percentage of silt, particles density and wind speed). The final aim of the ongoing research is the definition of reliable Emission Factors (EFs) to represent the contribution of tailing basins, mine dumps and stockpiles to the overall emission of particulate matter (PM) from industrial sites and open yards exposed to wind erosion (industrial wind erosion).
