Particle size effects on capture and matrix loading in HGMS

The performance of a well characterized HGMS matrix on the collection of paramagnetic particles from a slurry of known particle density and particle size distribution was studied. Particular attention was paid to the capture as a function of time of different size particles and the resulting changes in the particle size distribution of the collected material. The recovery of material of different particle sizes and operating conditions was correlated in terms of a dimensionless ratio of magnetic and fluid drag forces acting on the particles.
