ADVANCES IN MAGNETIC SEPARATION OF ORES

magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water

CHAPTER-8 BENEFICIATION OF IRON ORES

Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite (magnetic)

Recent advances in magnetic separator designs and applications

high intensity magnetic separators (WHIMS) generate high field strengths and pass slurry through matrix arrangements to collect the magnetic fraction. WHIMS are traditionally applied in mineral sands to collect ilmenite in the early stages of a flowsheet, and have a host of other common uses including iron ore (haematite) beneficiation.
