Notes:
Magnetic filtration of submicron (65.5 nm) hematite particles passed in aqueous solution through a bed of stainless-steel spheres has been investigated under conditions of constant flow rate (∼3 cm/min) and fixed solution pH(=11). Measurements were taken as a function of field strength for magnetic fields up to several kOe in both the longitudinal and transverse orientation, and for collecting spheres in three different sizes ranging from about 50 to 200 μm. Filtration efficiency increases with field strength up to a saturation value which depends upon specific system characteristics (size and composition of the collecting elements, field orientation, etc.). The recovery of the filtered particles also was studied and found to vary with applied field and collector characteristics. The results are interpreted on the basis of current theories of magnetic filtration.
