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

Magnetic Separation in the Mining Industry - Mainland ...

Apr 29, 2015  Magnetic separation is most commonly used in the mining industry to separate “tramp ore,” or unwanted waste metals, from the rest of the bulk material. Tramp ore typically consists of the man-made byproducts created by the mining process itself, such as wires from explosive charges, nuts and bolts, nails, broken pieces from hand tools such ...

Chapter 13: Magnetic and Electrical Separation ...

Magnetic Separation. Magnetic separators exploit the difference in magnetic properties between the ore minerals and are used to separate either valuable minerals from non-magnetic gangue, e.g. magnetite from quartz, or magnetic contaminants or other valuable minerals from the non-magnetic values. An example of this is the tin-bearing mineral ...

COMPARISON OF MAGNETIC SEPARATION AND RESULTS

Figure 2 shows magnetic separation results of the present colemanite ore samples in detail. The feed grade was calculated as about 40% B203 prior to desliming and about 43% B203 prior to magnetic separation. In Figure 2, it is clearly seen that while the recovery values for non-magnetic products (concentrate) were fairly

The force experienced in the magnetic field is given by the equation f=m/k.H.dh/dx. with k=magnetic susceptibility, H-magnetic field strength, and dh/dx being the magnetic field gradient. As seen in this equation, the separation can be driven in two ways, either through a gradient in a magnetic field or the strength of a magnetic field.
