Abstract
A magnetic matrix for magnetic separation of particles in a material feed includes a plurality of grooved plates having first and second sides that both have an alternating series of teeth and grooves therealong, each grooved plate having an offset alignment in which teeth and grooves on a first side of a plate are laterally offset from teeth and grooves on a second side of the same plate. Also provided are methods of using magnetic matrices to separate magnetic ores, with the methods characterized by a negative correlation in which magnetic matrices constructed with grooved plates having larger pitches are used for the separation of ultrafine particles.

A matrix for use in magnetic separation of particles in a material feed, comprising:
- a plurality of plates, comprising inner plates and outer plates, with at least the inner plates being formed as grooved plates having first and second sides that both have an alternating series of teeth and grooves therealong, wherein
- the inner plates have an offset alignment in which teeth and grooves on a first side of a plate are laterally offset from teeth and grooves on a second side of the same plate, such that peaks of the teeth on the first side of the plate reside on a common axis as valleys of the grooves on the second side of the plate, and such that peaks of the teeth on the second side of the plate reside on a common axis as valleys of the grooves on the first side of the plate, and
- the inner plates are aligned such that peaks of the teeth on a first plate are made to align and reside on a common axis line with peaks of opposing teeth on an opposing side of an immediately adjacent second plate, and such that valleys of the grooves on the first plate are made to align and reside on a common axis line with valleys of opposing grooves on the opposing side of the immediately adjacent second plate.
