Magnetic Separation an overview ScienceDirect Topics. The ilmenite production from heavy mineral sands exclusively utilizes a physical separation method using magnetic separation, gravity concentration and electrostatic separation. Flotation is practiced mainly for beneficiation of fine mineral sands containing rutile, ilmenite and zircon.

More About Magnetic Separation. Last month, we wrote about how magnets are assembled for magnetic separation applications – attracting iron, steel, or other ferromagnetic bits to get contaminants out of other materials. It was a great example of some specific ways that magnets are selected and assembled for this task.

In small, low pressure boilers, steam-water separation can be established with the use of a large steam drum approximately half full of water.Natural gravity steam-water separation can be sufficient for this case. On the other hand, for high capacity, high pressure (HP) boilers, steam-water separation at the steam drum is accomplished with the use of mechanical steam-water separators.
