CHAPTER-8 BENEFICIATION OF IRON ORES
MAGNETIC SEPARATION - PRINCIPLES AND APPLICATION IN BENEFICIATION OF IRON ORES A. Das and S. Roy INTRODUCTION 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 …

Dry Magnetic Separation of Iron Ore of the ...
Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility (as a rule, 20– 90·10-7 m3/kg8). In mining industry the technology of preliminary minerals concentration with self-propelled crushing-concentrating plants should be applied9. …
Processing of Lean Iron Ores by Dry High ... - …
Dry high intensity magnetic separation (DHIMS) is investigated to process a lean hematite ore. It was found the feed particle size and the drum rotation speed …
Magnetic Separation - an overview | …
Magnetic separation is a simple, fast and efficient procedure and the whole separation process can be performed in the same tube. Large differences between magnetic permeabilities of the magnetic and nonmagnetic materials can be exploited in developing highly selective separation methods. The separation procedure can easily be scaled up if large quantities of …
Magnetic Separation and Iron Ore Beneficiation …
Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
Maximizing the recovery of fine iron ore using magnetic ...
Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from –200 µm down to –10 µm. The general view is that this fraction is low grade in terms …

Evaluation of Magnetic Separation Efficiency on a ...
Yet, the investigated skarn ore contains about ~30 wt% of iron oxides (magnetite and hematite). The effective separation of these iron oxides is important for the following reasons: Low magnetic separation is usually implemented as a pre-concentration step to reduce the mass streams in the downstream flow sheet [3]; A by-product of high grade iron oxides will …
Magnetic Separation - Mining Fundamentals
Magnetic separation is a process by which magnetically susceptible material is separated from a mixture by the application of a strong magnetic field. Iron ores are usually subjected to magnetic separation process due to the high magnetic susceptibility of iron.
A discussion of magnetic separation techniques for ...
magnetic separation early in a process can greatly benefit an operation if a low-grade final tailing, or a clean marketable product, can be produced, since it alleviates both drying and dry storage costs. While WHIMS use can be advantageous, a common drawback of conventional designs is entrapment of non-magnetics in the magnetics product, particularly when treating …
