Six steps to process iron ore. 1. Screening ... Magnetic separation The concentrate collected from the middlings and tails after spiral gravity separation has a lower iron concentration (magnetite) so it must be further concentrated to achieve the customer's 65% Fe concentration. It is immediately directed to a magnetic separator circuit.
An integrated and efficient process for borax preparation and magnetite recovery from soda-ash roasted ludwigite ore under CO–CO 2 –N 2 atmosphere. ... and 88.6% of iron was recovered during the magnetic separation and magnetic concentrate with a total iron content of 61.51wt%. Raman spectra and 11 B NMR results indicated …
Magnetic separation theory The magnetic separation of magnetite and other magnetic minerals is a complex process. During the separation process, each particle is subjected to a number of forces, including grav-ity, drag, etc. The simplified equation below describes the magnetic force the particles are subjected to: Magnetic force:
