A set of experiments was designed to investigate the factors--atmospheric and surficial--controlling fugitive dust emissions from the tailings ponds of UNIMIN Canada, a mining company that extracts and produces nepheline syenite (feldspar) at two adjacent sites (Nephton and Blue Mountain) located north of Havelock, Ontario. Using wind tunnel measurements, the combined influence of relative ...

Wind-blown sand, or "saltation", ejects dust aerosols into the atmosphere, creates sand dunes, and erodes geological features. We present a comprehensive numerical model of steady-state saltation that, in contrast to most previous studies, can simulate saltation over mixed soils. Our model simulates the motion of saltating particles due to gravity, fluid drag, particle spin, fluid shear, and ...

Dec 01, 2016 Ambient dust levels in the lab were observed to rise slightly as the fan speed was increased, suggesting either some recirculation of emitted dust back to the wind tunnel inlet, and/or re-suspension of fine particulates within the lab. Sampling the PM 10 concentration (c) at z 2 thereby provides a means of effectively correcting for this effect.
