Abstract
Magnetic separators with variable height of the magnetic matrices, and methods of using the same for processing material feed with lower grades and/or very fines particle sizes, allowing for better performance in terms of mass and metallurgical recoveries as well as higher grade products.
Claims35
A height adjuster component adapted for installation on a magnetic separator, comprising:
- a curved interface surface adapted for expanding a height of a pole-rotor interface component in a magnetic separator, an engagement surface for adapted for engaging a mating surface of a pole-rotor interface component, and a height-expanding surface along which a height of the height adjuster component is made to increase,
- wherein the curved interface surface has a curvature approximately coinciding with a curvature of a pole-rotor interface component for which the height adjuster component is adapted to engage.
A pole for use in a magnetic separator, comprising:
- at least one variable-shaped pole arm having a free-end of a first height and a base-end of a second height, the second height being greater than the first height, and a transition surface adapted for transitioning a height of the pole arm between the first height and the second height, the transition surface being adapted for reception of a complimenting pole adjuster for extending the height of the free-end of the polar arm from the first height to the second height.
A matrix for use in a magnetic separator, comprising:
- a plurality of vertically oriented grooved plates aligned in parallel with one another, with each plate separated from one another by a gap that extends entirely vertically through the matrix,
- wherein the plates have a vertical height (H) greater than 220 mm.
A magnetic separator, comprising:
- a first separation unit comprising a rotor with a plurality of matrices around a circumference thereof, a number of slurry inlets for introducing a first slurry feed to the matrices, and a number of magnetic poles for generating a magnetic field through the matrices;
- a second separation unit comprising a rotor with a plurality of matrices around a circumference thereof, a number of slurry inlets for introducing a second slurry feed to the matrices, and a number of magnetic poles for generating a magnetic field through the matrices;
- wherein the magnetic separator is configured to feed a particle yield from a magnetic separation cycle performed at the first separation unit as the second slurry feed to the slurry inlets of the second separation unit.
