Highly successful tests have shown that highgradient magnetic filtration can provide a viable alternativeto conventional filtration to curb the amount of stack gasparticulate emissions from iron-based industries, especiallysteelmaking processes. Using basic oxygen furnace dust in ourwork at Sheffield University, filtration efficiencies of 99%and greater were obtained for submicron particles down to anoptically measurable 0.24 μm diameter; for particles of 1 μmand above, 100% filtration efficiency was achieved. High gasthroughput, together with low pressure losses, low appliedmagnetic fields and good filter matrix loadability all furtherindicate the potential commercial practicality of HGMF in thesteelmaking industry.
