The mining and processing of natural constituents (perlite, clay) can produce emissions to land from surface impoundments of liquids, solids, slurries and from storage facilities. Physical terrestrial impacts from the process of extracting minerals (perlite, clay) result in the removal and stockpiling of topsoil and sub-soil, and from removing overburden and inter-burden, resulting in modified soil profiles, topography and drainage. However, this is minimized as mineral fines and overburden are often used to reclaim mined-out areas of perlite, therefore minimizing waste.
