Magnetic Fluid Density Separation System for Fine Powders.
Abstract
A feasibility study was performed on the separation of mixtures of fine powders according to their densities in a gradient magnetic field. Using liquid oxygen and ferrofluids as the separation media, low yield separations of fine particle mixtures at densities up to 4 GM/cc were achieved. A particle interaction force of magnetic origin is considered to be the primary factor influencing the quality of the separations. Additionally the use of ferrofluid as the separation medium alters the apparent density of powders less than about 50 micrometers inversely as their size making an accurate separation by density impossible. Liquid oxygen does not demonstrate this effect and is considered a promising medium for the separation of fine powders. (Author)
